Walk through the kiddie section and head for the hills. Cache is on a somewhat steep slope, but there's an area for some to wait if necessary, while others make the search.
Cache used to be called Wascally Wabbit. Same hide, same great park, new owner.
Edited 4/24/10:
The numbers are a little soft here, so I've bumped up the difficulty and added a hint.
Congrats to RumGirl for FTF!
