19 of 21Las Vegas
The Big Shot is some kind of pneumatic-turbolift-ish device with a central shaft and a sled with sixteen chairs mounted around it. You sit on the chairs, strapped in with harness and all, and then you're launched along the shaft up, about a hundred feet.
At the top of the trajectory you experience a rather powerful stop and then some serious negative Gs as you're not only propelled upwards, but also pulled down by the machine.
I went with Dave, at about 2200 hours when the sky was pitch black and you could see the neon lights of Vegas stretch to the horizon, with some aircraft taking off and landing - below me.
