SAN DIEGO -- Daredevils riding a motorcycle and a snowmobile will attempt to jump the 300-foot opening that takes boaters from the Embarcadero Marina to San Diego Bay.
Motorcycle rider Robbie Maddison and snowmobiler Levi LaVallee hope to soar in tandem in the "Red Bull: New Year. No Limits.'' televised event on Saturday night.
LaVallee, a Minnesota resident, hoped to try the jump last year but crashed during testing in Fontana, suffering a fractured pelvis, broken ribs and lung injuries.
LaVallee and Maddison plan to fly off a ramp on Embarcadero Marina Park's north side to a landing area on the south side. A foam safety bag will be set up under the beginning of the landing ramp in case they fall short.
"From top to bottom, it's one of the scariest things I've ever done,'' LaVallee said while looking at the ramp.
The event is scheduled to be televised on ESPN and espn3.com beginning at 8 p.m.
