360 miles in 5.5 hours is a AVERAGE of over 65 mph.
Yep. Ah, the invincible days of youth.
ccohen322, do you ski or snowboard? Alyeska Resort is in Girdwood, popular for skiing and incredible views. And yes, Talkeetna would be a reasonable day trip.
I would also nix Fairbanks this time, unless you can find a really good airfare. Occasionally fare sales rival the cost of gas to drive, and with a 50-minute flight each way, can make for a reasonable day or overnight trip.
Anchorage is a bit of a foodie town, so you might check out some of the local restaurants and breweries. Moose's Tooth is a staple for creative pizzas and locally brewed beer. Glacier Brewhouse has great seafood along with their own locally brewed beer, and you can see into the brewery from the restaurant. Snow City Cafe has won the Best of Anchorage award for breakfasts for 12 years running. In Girdwood, check out Double Musky (spendier, but the portions are huge).
