No key

My wife and I went over to the track this morning to look for the key to my truck.  After an hour and a half thorough search, we gave up.  Then, I checked with both the University PD and Huntsville PD.  No one turned in the key, but they have my name and number.  This evening, I went back to the track and ran an unplanned course on the roads.  It turned out to be 3.1 miles.
