The spot on Keystone is any of the sandy beaches on the south arm of the lake. I believe it is a short run from Appalachia bay. Or sometimes they put in at Keystone ramp and run right across to a beach. On this map http://www.outdoorsok.com/images/lakemaps/keystone.pdf the whole arm in the middle of the lake between salt creek cove n and sandy park is sandy beach.
