Hi all,
MrsMustardman and I are going to be doing a long-distance move from Pennsylvania to Washington State, and we're thinking about extending the trip by a few days to work in some camping.

The only wrinkle to the plan is that we'll have both dogs and cats along with us in the two cars. The dogs are fine to take on leash outside the vehicles, but the cats will need to stay contained the whole time to keep them from running off. We'll also be hauling a 4x8 Uhaul trailer.

We expect the trip to consist of a mix of tent camping, hammock camping, and hotel stays, but we're leaning towards hammocks to save money and enjoy the trip a bit more.

An obvious choice would be to swing through Yellowstone on the way out, even if we don't camp there (somewhat concerned about cats + dogs + grizzlies), but what other places should we be seeing, visiting, possibly camping in? How frequent will we find places to hang our hammocks along the route?

Any thoughts would be hugely appreciated.
