GREENVILLE (AP) – Six snowmobile operators and one all-terrain vehicle rider learned the hard way that they can be charged with drunken driving while operating recreational vehicles.

The Maine Warden Service charged four snowmobilers and one ATV rider with operating under the influence at the annual Schoodic Lake Ice Fishing Derby in Lakeview Plantation. Two other snowmobilers were also charged with operating under the influence over the weekend.

Sgt. Pat Dorian, who covers Piscataquis County for the warden service, said the arrests should serve as a warning that drinking and driving of any sort will not be tolerated.

“If you’ve had a drink and are operating a snowmobile in this county, we’re going to get you,” he said.

Sgt. Dan Menard, who covers Schoodic Lake for the Maine Warden Service, said 11 wardens assigned to Schoodic Lake on Saturday for the ice fishing derby, now in its 43rd year.

“To have 11 is a lot especially since there are only 93 in the state,” he said. “That’s the most I’ve seen on a sled detail.”

In other snowmobile incidents over the weekend, two people were injured in Piscataquis County. Neither one involved alcohol, wardens said.

In one accident, Edward K. Wilcox, 21, of Levant, was thrown from his sled while crossing Moosehead Lake. His snowmobile landed 425 feet past where the accident occurred, officials said.

“He was traveling at a high rate of speed, which they often do on the lake, and he hit a small pressure ridge, which caused his sled to go airborne and him to go airborne,” District Game Warden Jared Herrick reported.

A second accident occurred early Saturday evening when a Standish woman was snowmobiling on Spruce Street in Greenville and her sled suddenly turned over.
