No bus until 7th grade, as the elementary schools were only a few blocks from home, and I walked unless it was very bad weather. For junior high & HS, most of the time in the mornings, our neighborhood carpool (my mom, and a couple of the neighbor ladies) took us. Usually rode the bus in the afternoon, but walked the 1.5 miles if weather was nice.
Most of the bus fleet was International or Ford chassis, and a few GM's, with Blue Bird or Wayne bodies. Most were new, but rememember one old Blue Bird with GM chassis that was from the late 40'- early 50's. It had a gasoline engine, unlike most of the newer models that were diesel. It had seen better days to say the least.
