Bill Nunn and Family, who run Skyrock Farms in Hamel. www.skyrockfarm.com, are having an open-house on Sunday, October 29 (1-5 p.m.). Their facility includes a huge music room with numerous mechanical instruments, among them a fully functional 1929 Barton theatre pipe organ and several imported and restored Gavioli band organs (think merry-go-round instruments, but on a larger scale, cranking out some the world¹s most infectious and happy music!), plus an antique carousel (just for kids) and an amusement-park train you can ride on the half-mile track around the grounds (adults allowed here!). Location: 2825 Willow Drive North, Hamel, MN 55340.
