Morningside Flight Park (http://www.flymorningside.com/index.html)

We did the Tandem Flight; it's honestly not that expensive at all. Unfortunately, the only real directions I can give are "follow your GPS; after it curls up in a ball and starts whimpering just keep going until you find the junkyard and ask the guy there.

If you do go, let me know - I will take any excuse to do this again. :)
