Pretty sweet earthcache! Was very excited to be able to come to Central Park and do this one. Had fun exploring the rock and doing the research and learned a lot. When I was back in Wisconsin, I did a couple of earthcaches in the Kettle Morraine with a friend and kept pointing out erratics. She was impressed. This is a very well done earthcache and gets a favorite from this cacher! Thanks for the work in putting it together.
