All-terrain vehicle riders who formed a parade along Minnesota's North Shore are claiming a world record for their turnout. The All-Terrain Vehicle Association of Minnesota tried Saturday to line up more than 2,000 ATVs in Silver Bay into the longest parade documented for Guinness World Records. Group spokesman Les Schermerhorn said they fell short, but their count was 1,632 ATVs. They hope to have the Guinness organization verify the claim in the coming weeks. The current record of 1,138 ATVs was set by the Harlan County Ridge Runners of Evarts, Kentucky, in 2006. Three-wheelers and side-by-side ATVs do not count. The Minnesota group's attempt last year fell 55 four-wheelers short of the Kentucky group's total.
