I read about this in the Houghton Lake Resorter (local area newspaper). There will be a Gun and Knife Show at the Houghton Lake Playhouse on M-55 in Prudenville (next to the Historic Village). Show will be from 9-4 on saturday October 30. For more info call 989-686-6535. Admission is $5 for adults, $1 for children 14 and under.
