I heard about this & thought it might be a fun way to break up a road trip across NC for my kids, ages 3, 6, & 8. If I get the mobile app on my iPhone, will it have everything I need to find multiple geocaches along the way or do I have to pre-select them before I leave my desktop at home? are there many locations along I-40 (the majority of our trip will be here) in NC? thanks!
