Alaska is definately an awesome place for photography. I am doing an internship in Juneau for the summer and am sad because am going to leave in 3 weeks. Besides Denali, did you visit elsewhere?
It started with a cruise in Vancouver that stopped in Ketchican, Juneau, Skagway, and Sitka. Then we got on land in Whitter, then went north to Anchorage, through Denali, then to Fairbanks. Awsome trip and I took over 500 pictures. I will upload more on the site later.
