If you are licensed and looking to jump...look elsewhere. When I showed up there this year, there were really no experienced jumpers around to jump. Visited SDC the next day and the talent was like night and day. If you are looking to do a tandem, CSC is great! If you are a licensed skydiver and you would like to do anything more than a two way, you might want to consider another DZ in the midwest.
