Yellowstone/Teton is not dog friendly at all. I board a lot of dogs for people traveling that way.

I think we should all meet in MY town. Then I can actually go.

I'm in south-western Wyoming. About five hours from Pembroke and about 3 hours from Wolf Q. It is almost the middle between SLC and Denver. (Well, Rawlins is technically the middle, but there's not much in Rawlins.) Of course, that's further from the Montana folks. If you want to go further north west in Wyoming, there's Thermopolis, which has fun hot springs. There's Cody, which has a big, nice western museum. But, that will add another 4 - 6 hours onto the drive for the Utah/Colorado folks.
