Today starts a month long challenge called "31 Days of Geocaching". The goal is to find a cache for every day during the month of August. For each day that you find a cache or attend an event, you get a souvenir. Hubby and I have a 108 day streak going (we have found a cache every day since April 16th), so I have no doubt we will be able to complete this challenge and collect all 31 souvenirs.
If you have never done geocaching, go check it out at www.geocaching.com. It is a lot of fun, gets you out of the house, and is much a mental exercise as it is physical. We have been members of the geocaching family since 2001.
