In response to a story (elsewhere) about the Wyoming circus, I searched Plugshare. If I turn off all the oddball AND RV plugs, Wyoming is indeed a charging desert. The Dakotas and eastern MT are similar. If you don't stick to the major interstates and have a Tesla, you're pretty much SOL even including L2's. But if you turn on the RV outlets things are (slightly) rosier. So that's a way to get away-from-home/work charging in those places. You just need an appropriate plug adapter; many of them are 240V plugs for RVs, so you can use a L2 charger (or the L2/L1 adaptable that's available with the 2022+ models but probably works in all of them).I've been searching all the small towns when I'm out and about for at least L2/NEMA14-50 charging opportunities at city parks, etc. I put most of what's on plugshare for the northern half at least, and a fair amount in the southern half and a lot of western SD and eastern MT as well. Not that L2 is where it's at, but if a guy screws himself, at least there's a way out.
EDIT: and I've found that if you're going into the Bush having a Tesla <> J1772 adapter with you is essential. Many if not most hotels in touristy areas have chargers, but a large number of them are Tesla Destination chargers only - no J1772.
