I prefer the phrasing “the province could cease propping up the neighbouring state’s economy.”

I continue to be astounded (though not surprised) at the degree to which drivers don’t even consider the existence of pedestrians - much less their safety. Crosswalks and pedestrian-crossing signs have become hieroglyphs, with meanings lost to time; right-of-way a concept from an extinct people.

Logan, after a fetch session. His stride has lost much of its spring, but he’s still a rockstar after all these years.

Back in the workshop on this gorgeous fall Sunday. I’m confirming some measurements, this time using my most recently-completed build: a hardtail Strat-style guitar (S/N 0011). It has a one-piece Honduran mahogany body, rock maple neck with ebony fretboard, and Fralin Blues Special pickups.

Damn. I bought this Ilford mug in ‘95 or ‘96 in Whitehorse, YK. It came with a few rolls of HP5+, and has been my favourite mug ever since. After 30 years of daily use, it slipped out of my hand while drying. It’s now chipped and cracked. Any chance of a reissue, @ilfordphoto.com? I’d buy several!

D'oh: that should've been "-henge" 🤦‍♂️ As an aside, this was the 2nd year in a row where a thin low cloud layer obscured the Sun as it set. The brightest spot in this image is that cloud layer, illuminated from behind (which is why it appears that the Sun is setting a touch north of due west).

The Sun sets on Edmonton’s 107 Ave, which runs due east-west, on this autumnal equinox evening.

I keep meeting smart informed Albertans who tell me they do not intend to vote, because they don’t want to legitimize the process, or because they know the premier is not bound by the results. But what if making us give up on voting is the whole point? My argument to vote - no matter the absurdity.

I can’t wait to get back to this baritone guitar build. It’s very different than the Fender-style builds I’ve been up to for the last while, and much more rewarding and committing*. * “committing” as in how much more significant the question “How do I not f#@% this up now?” becomes with each step

I do love the look of a Honduran mahogany body, white pickguard, maple neck, and pau ferro fretboard. (This Tele-style guitar is an early build; I’d not yet come up with my signature headstock shape and it lacks my “JK” logo.)

A somewhat disappointing lack of “ear” on this one, but I do love listening to it sing (sound up for subtle crackling noises).

As an academic I feel like that I'm living in that scene in The Big Short where they see all the empty houses and know it's a bubble, but for me it's hearing about all the innovation and growth in higher education, then teaching a class where only 8/250 students show up weekly

If stress makes an appearance during my daily cyclecommute, its origin is pretty much always the same: some interaction with an automobile - or, more accurately, the automobile's driver. Typically because the driver is wielding the automobile like a weapon. Knowingly, purposefully.

I'm apparently seven years late to this party, but damn - what an ensemble. Every bit of it is fantastic - the voices, accompaniment, and mix - but Nick Campbell's bass work is absolutely stellar, and that open-E/upper-G# combo he hits several times are my favourite dyad on the instrument. Enjoy:

Tomorrow marks the 25th anniversary of 9/11, when Canadians responded, united, to support and protect our American neighbours. Tonight, I was reflecting on the sacrifices our country made - only to see them now derided by US leaders. I wrote this 6 years ago. I think it’s worth a reread now.

I'm loving this picture of Jerry, wearing Doug Irwin's "Wolf" guitar - though apparently before Jerry had slapped the namesake sticker on it, and before Doug subsequently peeled the sticker off and reproduced its likeness with inlaid pieces of wood - thus creating the "Wolf" we know (and 🩷).

Despite the fact that Linnaean classification doubles down on the common name for these beautiful birds — “Xanthocephalus xanthocephalus” means “Yellow-headed yellowhead” — I still like to think of them as “Black-bodied yellowbirds.”

This is a cogent piece for Americans to absorb. It is also a good roundup for Canadians to reflect on where we've come over the last year and where our future lies notwithstanding the economic punishment coming our way from Trumplandia.
