I'm not quite halfway between you and Moab - but you're welcome to crash at my place in Denver on your way through next time. And if you're looking for an urban area very near to surrounding nature..... Denver's a great place to live.
That sounds like an incredible offer. I've been starting to think of places to take my summer vacation and that might be the answer. I've been thinking of where to go after here and Portland is high on the list. Kansas City is up there also just because that's where I grew up and all of my family is there as well as a lot of friends. If I check out Denver soon, that might be taken into consideration.
On the same trip as the one to Moab, we drove back to KC and camped at Sylvan Lake in Eagle, then stopped at Colorado Springs/Manitou Springs to check out some sites.
