Busted Bus

After delivering coffee from Loose Caboose today, I was headed back to my car and couldn't help but notice a Mountain Line bus that was billowing smoke from the exhaust. I know how environmentally friendly Mountain Line is and figured the bus must have just blown the engine or something. I followed it for a few blocks and sure enough, the driver had to pull over and radio for help. Did anyone else see this downtown? Does anyone at Mountain Line know what happened to the bus? Have you even blown the engine in your car? My dad is a mechanic and let me tell you it's no joy ride! :-D
