We were back at Recteck.com looking at the Secret Bikemaps when we noticed a slew of other great content, starting with this page of aerial photographs. The site also has some great NYC kayaking shots. Check out this set from the Hudson, or this one of the boat graveyard in Staten Island, or this ride to the Statue of Liberty. [Related: here's another set of aerials, taken during the Gates, and FromTheAir has a bunch more. Also, Jason and Meg took a helicopter tour a couple of years ago and took pictures.]
