A Winona County treasure. Historically a get-away community gatherings. Reservations required for pavilions but otherwise free. Images: Steve Lunde. LEWISTON, Minn. – Another large drive-in beer bash in the woods, this one in Farmer Park, the third of the season in Winona County, was caught early by deputies. The revelers somehow had been forewarned tyat deputies were on their way. As drove in, the revelers were driving of the 38-acre fenced park on Garvin Brook. Deputies estimated 50 cars were still on-site. It was still early for these kinds of gathering — about 11:55 p.m. Deputies said nobody was belligerent. The party matched the description of Snapchat-arranged parties that have a law enforcement for moths in Fillmore, Olmsted, Wabasha and Winona counties. This time, however, the event was in a public park, albeit after hours, and just off the major U.S. Highway14 thoroughfare – a brazen choice, unlike predecessor pop-up parties at secluded rural sites. Like eakier parties, many participants had driven quite a ways. Several were identied from Rochester and the Dover area in Olmsted County.There were no arrests.
