First trip to Maine but will only be there 1 1/2 days so sticking with the southwestern area (Portland...). I'm interested in seeing historic areas, a lighthouse or two, the ocean, & would really love to see a whale even taking a boat ride if needed. I like to eat at locally owned, non-chain, places & hope to try lobster for the 1st time! Any suggestions? My friend & I are in our 50-60s.
