VERONA, WIRobbie Bovy, 13, announced his intentions Monday to launch his brother's Schwinn BMXpert into a ravine near the East View Heights subdivision. "For the first stage, your bike will be powered by me," the older Bovy said at a backyard press conference while seated on his brother's chest. "Then, just before I hit the ramp, I'm gonna jump off and watch it totally endo into the rocks. Got it? Got it?" Bovy's intra-ravine mission is part of an ongoing exploration program that began in 2002, with the deployment of seven of his brother's plastic army men down the toilet.
