Most campgrounds in Maine open on May 15, with some opening May 1. A few remain open year-round, however water is not available at the sites for those.
Yesterday saw up to 4 inches of snow in southern Maine with none in my area...pretty unusual. The rest of the week is sunny with seasonal daytime temps but pretty cool nights, dropping below freezing.
After this mild winter and having just brought the TT out of storage, I am beyond ready to get a weekend of camping in. First scheduled trip is Memorial Day weekend, but I don't see myself waiting that long. It's time to go camping!
