I've been to Alaska many times but never to Sitka. I'm thinking about flying from Portland to Sitka on June 18, and then flying from Sitka to Fairbanks on June 21 to watch the Midnight Sun baseball game before flying home. Is 3 days a good amount of time to enjoy Sitka? Should I rent a car? I'm into photography, wildlife viewing and history, and hope to enjoy all 3 when I'm there. Thanks for any help you can provide!
