For many years the Northern Recon Group has descended on the Butte County Fairgrounds bringing countless military vehicles to display as they camp out for "Camp Gridley" and they will arrive on April 12 to start their event through Sunday. Saturday, April 14 from 11 to 4 the public is invited to come check out the vehicles and the many displays including World War II, Korean and Vietnam wars. Betty Chambers was escorted through the fairgrounds last year as people are welcome to go for a ride in many of the vehicles as they parade through the fairgrounds.
