We had some curious muggles watching us while searching for a geocache in some bushes near a museum. I called out "here kitty, kitty, kitty!" Told them I was looking for my cat. More frequently, if we think we are being watched and think the cache is near ground level or under something, we'll accidentally drop our keys or a quarter, then do a clandestine search while bending down or crawling around retrieving our dropped item. If it is a family watching us, we usually explain what we are doing and get the kids excited about the treasure hunt. We've made a lot of geocachers out of muggles
