Just went skydiving through Skydiving Des Moines a couple days ago and all I have to say is everyone and anyone needs to give this a shot before you die. It's the most liberating feeling I've ever done and is a lot different than I expected. I imagined it being a lot like a rollercoaster, but it was way different. There was no knot in your stomach like you get from falling on a rollercoaster, physics guys care to explain? Anyways I will definitely be doing it again in the near future.
