Kenosha Transit 1978 First Production sloped back General Motors RTS model transit bus. Kenosha Wisconsin. April 2000.

I took this photo at the Kenosha Transit garage, on an April 2000 fantrip
with the Chicago chapter of the Omnibus Society of America. Seen here is a
1978 vintage GMC RTS model transit bus. The RTS model was the initial replacement for the Fishbowl windshield GMC buses, wich were in production since 1959.

The early RTS models had this unique slope back styling.
