Wow. The camping locations I was looking at are all booked up. I'll need to look at an offroad drive to a place to pitch a tent, or else find a motel at least 2-3 hours away and then drive in. 20-21AUG are booked at the Best Western in Idaho Falls, and for 21-22AUG, they're asking $1350/night.
You read that right. A freakin' Best Western, in Idaho, wants $1350 for one night. I'm really curious if they'll get it. I'd be assuming it will be foreign money. I can only imagine what the traffic will be if the motels feel they can charge that premium.
