GO! The only flaw I see in your plan is Anchorage, I would much rather live in a town of 250 than 250,000. The biology degree sounds like a good plan to me. You can't swing a dead cat around here without hitting an unemployed engineer. I had a plan very similar to yours 35 years ago, I wanted to go to school in Alaska but let family talk me into a local school that I never finished. It wasn't a complete wash out, I joined the Navy and never looked back. I retired from the Navy and moved back home to a boring job and relatively tame life, wishing everyday I was in Alaska or somewhere in the Rockies.
Follow your dream, don't be a should of, would of, could of. You'll regret it the rest of your life.
