I'm not one for overly pompous "self promotion" but I wanted to note one of our hides because it is in a very unique place that few New Yorkers know about. Here is the link: http://www.geocaching.com/seek/cache_de ... 2ac4faa097
It's in Seton Falls park, which is more of a nature preserve than a park. It was recently renovated by the City with new trails, etc. We discovered it by accident, we were looking at a street map of Mt. Vernon to find something, the map included adjacent parts of the northern Bronx, and we saw this sizable park that we never heard of before so we decided to check it out.
It is truly an amazing place, especially considering where it is (thus the cache name). When you enter the park, there is a sign describing all the flora and fauna you will find in this place; the main reason we made this a multi is to insure people see this sign. At the cache site in the center of the park, you can really feel you are in the middle of the woods and not one of the most densely populated parts of the boros outside of Manhattan (NOTE: It is completely safe, though I wouldn't go there at night.......the cache has never been muggled). There's also a nice waterfall we point out in the cache description.
Again, I hope this hasn't come out as too "self-promoting" but I think you will find this place to be quite unique and encourage you to go find our cache!
