I have a great time geocaching with my quilty friend. She has the GPS though so I tag along with her. We get ourselves into some very odd places searching - and boy do we get mad when we can't find it!!! :) It is a fun activity to do with young kids - gets them outside and on the hunt - we take along a picnic lunch and stop at the park to eat. Makes for an inexpensive outing and lots of fun.
My favorite cache was near a fire station. The paramedic came out and told us they were all sitting in their kitchen watching us bird-dog around in the garden below. We would not let him tell us where it was though - even if it was nerve-wracking to know a bunch of firefighters were watching us!
