I've been thru Inwood many times, and I know some of it's history and nature, but this may be a good chance to get a tour, history and education about the park, from an actual expert on the subject.
Afterwards we can continue to explore the park, do a little hiking and then head up to Indian Road Café [600 West 218th Street] for dinner & drinks.
IRC is co-owned by the former producer of The Sopranos, and.. well.. this is probably the LAST business on Manhattan, since any further north and you'll be in the Harlem River.
