YAY Garrison. It is where I was born and raised and a place I miss dearly. If you have ANY questions, please ask!
As for the run down: There is one grocery store but its of a decent size and has everything you need. There are four bars, a handfull of places to eat out and as Roloff stated, tons of hunting and fishing areas. NOT to mention.. ALL of my amazing family! *laughs*
My grandparents especially like to take a cruise up to New Town to the casion and my brother thinks very fondly of the Stoney End. Oh, and nothing..absolutely nothing beats pizza at Totten Trail!
Be sure to wave as you're taking off at the airport, our property is within sight!
Garrison is great, and they are so very friendly there. Of course, everyone will know you're new in town long before you even arrive, but they are very welcoming and super friendly. Kinda like Cheers, its a place where everybody knows your name. Infact, if you're up for it, the same retired crew meets at Four Seasons for lunch and supper every day. Of course, with my aunt cooking, why wouldn't you?

One thing to think about
: consider where you are going to live. We live about 3 miles out of town, and there are times during the winter (even this past winter) where our place is blown shut with snow for two weeks at a time. It takes our own crew and our equiptment to get us out. Coming from Alaska I'm sure you're not afraid of a little snow, but realize the reality of it all.
Again, you have questions- I got answers.
