Nathaniel's Backyard Cache Traditional Cache

We're always looking for wheelchair-accessible caches so that we can involve my son Nathaniel in this wonderfully exciting hobby, so we decided we ought to place a few such caches as well.  Nathaniel helped pick this spot and he chose the container from three he was offered.   

Park in King's Park, where there are playground equipment, a volleyball court, and tennis and basketball courts. Thanks to brandonrhoten1 for the heads-up about the poison ivy, which I'd not noticed given my approach; most of the flora in the GZ is woodbine (Virginia creeper), which is 5-leaved and not poisonous. 

I've increased the difficulty rating from 1.5 to 2 and added a hint, because there is almost one DNF for every find.
