Jalan Crossland is a local artist whom a lot of people follow. Bosler is a small town north of Laramie, or at least it was.
When I was an undergraduate at the University of Wyoming a few people still lived there, and a second hand appliance store did a pretty good business with students. By law school that was already changing, although somebody had taken up residence in the old, probably 1920s vintage, school that was there, having converted it pretty clear to coal fired heat.
Now it's really past even that state of decline. I'm not sure if anyone lives there any longer, although my guess is that the answer is probably yes.
Bosler once figured fairly significantly as an Albany County town. In the early 20th Century it was a going concern, and also nearly lawless.
Crossland, in this song, works in multiple layers of satire. The town is satirized, but so is the person who dreams of it as a refuge. Urbanites dreaming of Wyoming that way are not uncommon, and indeed land just outside of the windswept Bosler was marketed to out of states at one time who no doubt didn't realize that its 7,000 feet in elevation, exposed to the wind, and cold in the winter.
