Brookside Nature Center. The indoor part of the center had lots to offer (think turtles, puppets, books, a tent). Chase would have been content to spend the whole time inside (noted for when I'm in need of a cold weather activity), but we did convince him to get out and enjoy nature on a little hike. I'm not sure he grasped the whole "it's the journey" philosophy, however, because he kept asking, "Where's nature?"
What made the excursion even more perfect? Uncle Matt came with! Adventures are always more fun with him and we're grateful he made the time for us.
