Hi O180,
Don't know where about your adventure will end up taking you, but at one point you did mention Talkeetna as a possibility. Anyways... a thought occurred to me. Obviously you already know that flying in AK, you get handy with the supplement, but sometimes that leaves out some of the 'local' nuggets.
Now a Glacier flight with TAT or K2 is
The way to see the big one, but ya still gotta get to the big airport, and eventually leave.. (I am using big very loosely here

because you wont likely be flying in to the town strip on your first visit ) anyways... if you stop in at the ATK FSS and ask, they usually have a little paper map they'll give you with all the local routes, and freqs. While I'm normally not a big radio user, being a guest in a reasonably busy airspace makes knowing where the local traffic is expecting you to be, and what freq they expect you to be on is a 'no-brainer' in my book...
Other Talkeetna tid bits... If you bomb in there in the middle of the night (which isn't hard when it's still daylight) and don't find a spot to crash at, no one will bust your chops for camping under your wing for the night....
You can buy gas from Sheldon air service (yes Don Sheldon's daughter)... how cool is that?
And for no good reason I happen to be a bit of a pizza snob, and I really really like Mountain High Pizza...
Take care, Rob
