This cartridge will best be played from walking around the parking lot. It should be playable by driving as well, but be warned that there can be quite a bit of car traffic here and you may drive in circles or back and forth, etc. I strongly suggest that you bring a calculator and possibly reference material on Pi formulas.
This Wherigo is a terrain 1, meaning a person in a wheelchair can get to all the areas/classrooms. The physical container for the cache is a terrain 1.5.
