Edward Hopper exhibit. Easy drive from here and an excellent show. (Exhibit runs through Oct 16, 2011.)
Better still, with the Art Museum's interactive map, you can visit all of the sites where he painted during his vacations in Maine. This is an artist whose vision of Maine coincides with mine, which explains why I liked the exhibit! I loved his comment that all he wanted to do was paint sunlight on the sides of houses. Once you read that, the sunlight jumps out at you even through the darkening skies.
Wandered around the campus a little and popped into the Peary MacMillan Arctic Museum (just across the quad from the Art Museum). There is an exhibit going on now of Canadian Inuit Art.
