We have jumped at Chicagoland few weeks ago and it's a awsome dropzone. Staff is great and fun to talk to. Jumps were great lots of fun, will most likely come back. As for the post below I don't see how all it's true since everyone was wearing seatbelts when we were there. Looks like somone has a grudge against the dropzone.
