It's best to go at this cache from Bianco road and not the highway. The cache is NOT at the listed coordinates, but the answer is on this page. There are a few Elvis things in there, a small first aide kit, a super ball, a keychain and a Holz wooden puzzle. You may need more than just a car to get to this cache it's somewhat off road.
