Shoot, you're a lot closer to Yosemite or any number of great state/national parks than most people. Its real easy to get lost in Yosemite for a week or so. (in a good way of course) Exchanging your concrete and steel vista for an alpine view might help.
I spent a week hiking and camping in Yosemite with two friends when I was in college. I gotta admit that's one of the high points of my 50+ years.
