Leap-The-Dips, the world's oldest remaining roller coaster
reopens May 31,1999 at Lakemont Park in Altoona, PA

For the most up to date information on new Roller Coasters, I suggest the following web sites

http://www.ultimaterollercoaster.com (excellent News section too)

http://roller.coaster.net (database of virtually all US coasters)

http://www.thrillride.com (excellent rumors section too)

The above sites are some of the best the web has to offer park enthusiasts.
They provide much more timely information that RideZone possibly can.
