After a nice lunch, Grampa often likes to continue his walk--especially if he is walking on the canal. And he likes to find caches after lunch as well as before lunch. This may be Grampa's first after lunch cache--or depending on the direction Grampa is walking--this might be the one right before lunch. 
Good parking for this one is available at Adams Basin in the little park on the south side of the canal. Please don't go to far down the embankment that embankment is steep. Please do this cache during daylight hours as the towpath is officially open from dawn to dusk.
Congratulations to ttomw and his brother for the ftf on this one.
