I'm leaving Austin for the West Coast.
Not enough outdoor activities here. The amount of hiking trails is great for Texas. But not at the national scale or when compared to the West Coast & northern Rockies.
Texas is mostly private land, so there just aren't any greenbelts (that I know of, within 2 hours of Austin) where you can hike for 10-40 miles one way.
I'm strongly leaning towards Washington for that reason-- Huge "parks" (more like "wilderness zones") for hiking, as well as ocean kayaking, ocean sailing, and ocean fishing.
It's a cheap flight to Alaska from there. And WA is the only contiguous west coast state without state income tax.
