We have 5. Ages 17 to 7 and my wife is a letterboxer so these adventures often include both activities and a great deal of calamity. July 4, 2002 found us at the Washington's Crossing State Park in NJ for a letterbox and a geocache. The temperature was 98 degrees, humidity near 90% and of course, we packed a picnic lunch and brought the basset hound along. Lunch survived the dog, the letterbox was easy, then we gave the GPS to a 4.5 foot tall, linear thinking 10 year old who took us through the most unbelievable juniper and multiflora rose thicket on our hands and knees, with the dog on a leash, bugs biting, thorns scratching, dog barking, you get the picture.
We cleared the 300 or so yards of juniper bushwack into an open woodland and while we dusted ourselves off and licked our wounds, our 7 year old discovered the cache quite matter-of-factly. "Oh! Look, I found a geocache!!"
Great fun. We left by the very civilized route that everyone else had taken to the cache.
