I found a Geocache at lunch today.  It was just a short walk from where I parked the car down a dry creek bed. I walked down the wrong side and had to cross the creek and I was greeted by a very persistent barking dog who announced my arrival.  My iPhone app led me straight to the cache and within a couple minutes I had signed the log and was walking down the concrete sidewalk back to the car.  It felt great getting out in the middle of the day and just in time.  We are expecting a snow storm tonight.  Did you exercise your brain and your legs today?
