Apparently, it was one of those natural gas powered ones to!

The Sun Metro bus went up in the Cincinnati area a few weeks ago.  (I hadn't even heard about it until today when I stumbled across this video.)

You have to admit, the EPFD kick ass!  They never know what they're going to come across when they get a call. Fortunately, the fire station is just one street over so they got to this one mega quick and were able to vent (I guess) the natural gas before this situation got worse.  (Happens at 2:15.)

Cheers to all the firemen and women around the Borderland!  You guys rock!
