Picnic Drive, in Memorial Park, is where the Man wants you to picnic. The Man will tempt you with postwar picnic benches and plenty of sweltering pavement, where you can fry eggs. But if your idea of a picnic leans more toward the version involving trees, grass, peace and quiet, try the small park surrounding the Menil Collection in Montrose. There's plenty of room to throw a Frisbee and lay out a spread of fried chicken, and instead of port-o-potties, the place is dotted with sculptures by famous modern artists. Smack in the middle is the museum, the best free art space in the city. Now that's a picnic for the people.
