Let's get buggy with the Wonder Wagon and Insect Activities! Step into the world of environmental exploration with the Wonder Wagon, the Fairfax County Park Authority's innovative mobile nature center. The Wonder Wagon is not just a van; it's an experience. Packed with engaging activities, from bug-catching to birdwatching, the Wonder Wagon will help us envision our urban environments as nature-rich spaces. Crafts and activities will be indoors.
