So many ways to go with this... and almost every single one of them not wedding receiption-appropriate.

I think a lot about Putnam's "Bowling Alone" idea, in that without cross-cutting social activities (eg, bowling, Scouting), it's too easy to become chronically siloed, without exposure to alternate viewpoints. Sadly for his trucker, Haitians were "others" before he was forced to see them as people.

How many ACS members are wealthy now based on current medical systems in the US healthcare system? Let’s not presume for a second that every “scientific society” is equally represented for its members — especially now — regarding federal government expenditures.

It's going to be a generational rebuild schedule, since everyone that remained will be considered suspect, even if they weren't complicit. Curious for your take on how to do that -- especially since similar efforts will be needed in other federal agencies (including NOAA).

Remember: Darwin's note of "I am very poorly today & very stupid & hate everybody & everything" was written on Oct 1 (1861). Thus we are free to celebrate Very Poorly And Very Stupid Hatred Day today.

Nice word choice, by the way. They indeed see "governing" when they hold office as "ruling," an ENTIRELY different perspective on representative government.

Totally disagree. The Pentagon has gamed out the Hormuz challenge multiple times — and rational Administrations have decided that it’s simply not worth the after-effects, including the perception loss. When an Administration decides otherwise, they then fully own it, lock-stock-and-barrel.

IIRC, "tree" has a specific definition (likely USFWS or USNPS, both under DoInterior). Sounds like a way to start "harvesting" old-growth from NPS lands before a new Congress starts oversight hearings.

In my UG ichthyology course, it’s a LOT of material – fishes are an amazingly diverse, paraphyletic group! Some check out early, but for those who stick with it, they see me and my lab living most of this background in our daily research. By about midterm, they get it. Faculty, be that example.

A fantastic thread that all male parents of sons should read. I'd add that yes, talk with your sons (not AT them), but also live the example you want them to become, with how you interact with your spouse, your mother, and your female friends and colleagues. They learn what they see.

Indeed! Lower one's expectations, yep. /s (lots of /s) Mamdani scares lots of 90's-era consultants because he's actually delivering. Same to some extent with Spansburger. When Dems learn that pop positions have pos electoral results, we can talk systemic change. I'm just not sure we're there yet.

David Kerstetter, Ph.D. @fishguydave.bsky.social · 29/09/2026
But the Dems would actually try to implement a rational policy, which would then lead to all sorts of politically inconvenient exceptions. The conserv media would run with those exceptions, leaving the intent of the policy to wither and die. Wash, rinse, repeat. Propose this with European facts.

Similarly, people (especially Dems!) shouldn’t think that a protest vote against Reps is a vote *in support* of the Dem party — heck, poll after poll indicates that most *Dems* don’t like the Dem party leadership. Fascist policies with low inflation could’ve given Trump ~70% general approval rates.

Most unis take a pretty dim view of faculty conducting live vertebrate research without IACUC approval, since doing so also opens the institution to potential legal action, including loss of US federal funding. Protest "red tape" as you wish, but IACUC approval is still legally mandated. #FAFO

Any route will have up-down periods, sure. Peak SoFl tourist market from Nov to Apr, especially with winter cruises, but LOTS of folks here now with Mid-Atl and New England ties. Add a minor tourist tax (which airports also do), and I think it's feasible. Thanks for the chat!

David Kerstetter, Ph.D. @fishguydave.bsky.social · 24/09/2026
The irony is that per-mile costs actually bear out the distance aspect -- rail is more efficient over such distances. It's the initial investment costs that are (currently, politically) prohibitive. However, the *markets* between SoFl and the Mid-Atlantic/New England corridor are absolutely there.

I’d take it all the way to Miami, Fort Lauderdale, at least — both MIA and FLL airports serve large numbers of East Coast routes that could be served by rail (and the right-of-ways are still mostly intact).

Semi driver filling up his tank six days ago breaks $1,000 for 155 gals: "Almost 30 years of driving trucks and that's a first." Now, imagine this scene in front of every offshore commercial fishing boat loading 2500 gals before a trip. These costs are not sustainable for most US fisheries.
