On Saturday I was in Tucson at the UofA library and got a call from some buddies who were headed to Parker Canyon and the Rodeo in Sonoita. So I decided to join them and make the drive out. I was almost due for an oil change so I thought it wouldn't hurt getting it changed at a Jiffy Lube here in Tucson since I usually do it myself at home. Well, seven miles outside Sonoita my engine threw a rod because the oil filter hadn't been tightenend down all the way. 2001 Toyota Tacoma.
