Autumn farms bring families together with corn mazes, petting zoos, and ghosts demanding the construction of new baseball stadiums. Unite families for some barnyard fun with today's Groupon: for $12, you get admission for two to Bengtson's Pumpkin Fest 2011 at Bengtson's Pumpkin Farm in Homer Glen (up to a $23.98 value). Children ages 2 and younger are admitted for free and the farm is open through October 30.

Voted "Best Pumpkin Fest" by viewers of Fox News Chicago, Bengtson's Pumpkin Farm captivates visitors with the autumn-themed fun of four new attractions, pig races, a 3-acre corn maze fit for all ages, and the Kids Village complete with a jail and a fire station. Swine speed toward the finish line 10 times daily, spurred on by the cheers of bleacher-seated audiences, and human competitors race playmates or sentient scarecrows through the giant Crazy Corn Maizey's swaying stalks. The Pumpkin Chucker launches gourds skyward, and pint-size patrons mirror mid-air trajectories on kiddy rides such as the new 90-foot Mega Fun Slide and Flying Frogs (free through October 30, excluding pony rides). Ghoulish chefs and mad scientists cook up screams in the Haunted Barn before sending the spooked off to enjoy the soothing effects and bleated lullabies of goats, zebras, kangaroos, and other critters at the petting zoo.

Though Bengtson's Pumpkin Farm sometimes features a discounted price online, this Groupon still offers the best deal available.
