My girlfriend and I went to Great Adventure on Sunday. Our first stop, Kingda Ka. This thing is ridiculous, and I recommend it to anyone without a weak heart...
A hydraulic launch rockets riders horizontally from 0 to 128 mph in 3.5 seconds, then vertically 90 degrees into a quarter turn. Riders crest the coaster's tower an exhilarating 458 feet from the ground, then plunge vertically into a 270-degree (three-quarter) spiral.
The train swoops down a valley and climbs a 129-foot "camel hump" hill, leaving riders feeling weightless before making a left turn and gliding back into the station.
