Whatever you do when you visit this brainchild of the late artist Bob Cassilly, don’t ask for a map. The idea here is to wander and observe: turn one corner and find yourself in a hallway of funhouse mirrors. Turn another and run into a wall made out of bottle caps. It’s a mysterious, surreal journey that begins in a parking lot (with net ladders, slides, and an abandoned plane) and ends on a roof topped with a Ferris wheel and teetering school bus. In between, the aforementioned largest No. 2 pencil in the world. Also, there's a bar so you can enjoy a refreshing beverage after all the excitement of... filling in the world's largest Scantron?
