I just read that a house built in Lincoln, New Mexico in 1878 is for sell. Billy the Kid allegedly hid out in the adobe during his Lincoln County war days. The article doesn't say who built it or who or owned it at the time Billy hid under a bed or climbed into a flour barrel in the kitchen to escape a posse.
Located in Lincoln's historical district one can now buy their own piece of Old West history involving William Bonney for a mere $545,000, flour barrel not included. That's a bit cheaper then a credit card sized tintype of the punk sold for a few years ago for 2.3 million.
