In this Thursday, Aug. 18, 2011 photo, the late Sherwood "Red" Casterline had visitors sign a guest book to keep a record of people who viewed his tractor collection in Ensley, Mich. Arlene Culver beamed as she surveyed the farmyard lined with 72 antique tractors, old engines and other rusted farm equipment collected by her late father, Sherwood "Red" Casterline. On Saturday, hundreds of antique farm equipment buffs from as far away as Texas will gather for an auction to sell off the rare tractors and engines Culver's father dragged home one by one over 50 years of collecting.
