Here via mactavish: I spent a week in Maine last June, and the weather ranged from hot and sunny to drizzly to foggy to blustery, sometimes in the course of one day. Being a Northwesterner myself, I felt right at home. Pack some light wet-weather gear, a sweater and plenty of dry socks and you'll be fine.

As for things to do: If you're fond of tasty arthropods, eat lobster. You don't even have to pony up for the whole shell-cracking experience. Just about every small town has a diner or fish shack that serves lobster rolls: Lobster meat and a touch of mayo on a soft bun.
