I am going skydiving (tomorrow) with a bunch of my friends @ the sussex county airport @12p. Check out http://www.skydivesussex.com for more details. I hear that it is a nice drop zone.
If there are more than 10 people in the group, the price gets discounted to $165/person. We are about 7 now. If anyone is interested to join, email/message me. We can meet there and have fun.
