This is a fairly easy find. Park at the park office and head south on the bike trail. The coordinates should be very good.
Before the bike trail on Union Road, hole number 13 had a wider fairway and no out of bounds fence. When I (and my golfing group) was younger we could tee it up on 13 and duck hook it left across Union Road into the namesakes front yard. The cache is a small DNA tube with a log only. You will need to bring a pen to sign it. You do not need to go onto the course to retrieve it. Please return the cache to its original position. Be careful of bikers and runners. Parking is avIlable at the park office a little north of GZ.
