Thomas Welsher has had enough of the Viper at Six Flags Darien Lake for a while. The 23-year-old Webster resident outlasted the competition and won a two-year lease on a 2006 Suzuki Reno by riding the roller coaster at the Genesee County amusement park 395 times — that's more than 230 miles — in less than three days. The contest started with eight competitors at 10:30 a.m. Friday. Every three hours they got a 20-minute break and could get off the coaster.
