This past spring I visited the Storm King Art Center located about an hour north of New York City at One Museum Road, New Windsor, New York. This is an outdoor sculpture park with 500 acres of space to display their collections. You can take a day to walk the grounds or in the summer they have bike rentals. I found a few photos I took from my visit and am posting them. This is a great day trip to take and I will do it again in the summer.
They are currently closed for the season and will re-open April 2nd, 2014
