Hiking at Campgaw is a personal favorite of mine. It's usually quieter than the "other" county park. There's a disc golf course that goes up the south side of the ski hill and works its way back down the north side (with slight changes depending on the season). Cache is near the Blue trail amidst the course, so be aware of any nearby golfers.
Cache is kid-friendly with plenty of space for swag. Be careful retrieving and please replace as found.
Congrats to KanoeBillder on the FTF!
