The Hillsborough Balloon Festival and Fair will take place at Grimes Field. The fairgrounds will be filled with giant, colorful hot air balloons for this annual four day event. There will be an old fashioned fireman's muster, thrill rides and games at the carnival midway, live entertainment, 4x4 truck and tractor pulls, a classic car show, a mud bog pull and sky divers in action. The balloons will be offering tethered rides, and will take flight at dusk and dawn over the Monadnock Region. There will also be a fireworks extravaganza, a hometown parade and so much more. Admission is free. Parking is $5..
