Here's a picture of the garage that held Ward's Firehouse Five Fire truck and other souvenirs, which was located toward the right side of the Grizzly Flats train depot.
Ward had some career with his Dixieland Jazz Band (made up of Disney staffers including animator Frank Thomas), which traveled to gigs dressed as firemen in a real fire truck!
They were very popular for 22 years recording over 20 albums that sold worldwide (you can still buy their music on CD at amazon.com!). I asked Ward how he got away with having a professional jazz band at night while working at Disney during the day. Ward's response, "Walt didn't mind as long as you got your work done."
If you want to catch a visual sample of the band at their best, take a look at the supplemental material on the Frank & Ollie DVD.
