The last couple of weeks were absurdly busy. The Bay Delta Science Conference was amazing, but it also wiped me out. A few days in the mountains has been a great reset.

I really need to finish my presentation for the Bay Delta Science Conference, but Penzey has other ideas.

I got my covid and flu vaccines yesterday. Obligatory bandaid selfie- this time in the spooky decorations aisle. (Extra weird pose because I’m wearing a work shirt and I’m trying to cover up the agency shield.)

Happy Friday! I finished a first draft of a data analysis and write up for a technical appendix yesterday. In celebration, here’s a picture of Penzey being adorable.

No, I don’t really have any project updates to share because I was on vacation since the last time we met. Can I interest you in a picture of some kangaroos instead? (My team will have updates to share, but probably not pictures of kangaroos.)

I’m almost done revamping the last garden bed. The neighbor’s tree roots found their way into every raised bed. I started digging this one out to install a barrier and drainage like a month ago. Then my tooth saga derailed me. This one was an absurd amount of work especially in this heat.

Progress today: Wrote some code. Broke the code. Fixed the code. Now the code works too well and it broke some other code, but I’m not sure why yet. Then Atcha showed up and needed a lap, so now I’m cat furniture.

I left my wildlife camera out in my yard for like a month and I just pulled the SD card. I definitely squealed when I saw this picture of a possum with babies on her back. I hope it brings you joy, too!

Sacramento was really mellow, but there were tons of people out at the Capitol today. I reused my sign from last time and I added some glitter.

I made some neat #accidentalaRt in #rstats today. Those are supposed to be convex hulls around some clusters of points, but this is cool too.

Atcha is helping me turn the effects narratives from some water permitting documents into DAGs. I’m hoping this approach to reading will help me with paying close attention now and modeling in the future.

Today is my last day working at the Fish and Wildlife Service. I’m taking leave next week, then I start a new job at the CA Department of Fish and Wildlife. I’ll continue to do science to support delta & longfin smelt recovery in the San Francisco Estuary, but I’ll be focusing on supplementation.

I’m gone too much during the week so weekends look like this. I know they think the situation is dire when Penzey (the dog) tolerates Atcha (the cat).

I’m grateful for being exempt & knowing I’ll get paid on time, but it is really hard to just keep working through a shutdown. It’s like we’re being gaslit into thinking everything is normal and not total chaos around us. Penzey being stressed out with pumpkins for my fellow feds.

Confirmed- we’re exempt from furloughs & working through. The good part is that we get regular pay checks. (Exempt =/= excepted, which means working but not getting paid till the end.) The bad part is everything else. Pic of Penzey rearranging a blanket for maximum coziness for my fellow feds.

My office is funded by interagency agreements so we usually keep working through shutdowns. We’ll find out tomorrow morning if that’s the case again this time. Here’s a cute picture of Penzey the dog for my fellow Feds on this shutdown eve.

Happy caturday! Atcha’s technique for getting inaccessible things is consistent, yet entirely ineffective. (She does this to her water bowl, too.) The praying mantis on the screen seemed pretty entertained.

It’s tomato canning season! This weekend I picked about 25 pounds of roma tomatoes from four plants in my yard. Now they’re pizza sauce and salsa. There are still tons more tomatoes left, but I hit my limit for how much cooking and canning I can do in one weekend.

A new feral mint plant in my yard. I think it’s a Mexican mint because it has wide leaves and smells like oregano and instead of normal mint. (And a very scientific apple image search and wikipedia.)
