In one of the few fundraisers for the Bitterroot Performing Arts Series in Hamilton, the Big Sky Mudflaps will be "rockin' the joint" at the Bitter Root Brewery Sunday.

The 'Flaps will be part of an afternoon of activities at the brewery from 4 p.m. to 7 p.m. December 2nd.

The brewery will donate a portion of its beer sales to the Series and there will be a silent auction conducted through the afternoon, according to Monica Grable. She said the top item is a Stock Farm Club Getaway - an overnight stay in one of the exclusive Stock Farm Cabins, massages for two, and dinner for two at the Stock Farm Clubhouse.

Other silent auction items include a stay at the Harlan Cabin on Old Darby Road, signed and framed Ailey II poster, Lost Trail ski passes, art photography from Patrick Chaplin and Barbara Michelman and more.

The event is co-sponsored by the Recreation and Welfare Association of the Rocky Mountain Laboratories.
