The Keister Coaster at BWI was AWESOME! I was actually a little scared the first time, but then again, I am a big chicken!
Oh, and one more thing I would like to share for the ladies out there...I am one of those annoying moms that does not get her hair wet. It is not that I think I look bad with wet hair, I just hate putting chlorine in my hair, because I spend a lot of time and money getting it "just the right shade" of blond.
The Keister Coaster deposits you into the pool where it is about 4.5 feet deep (approximate.) So...i had my hair up in a clip and it never got wet!
