Durham Auction has a sale Wednesday, April 25 in Birmingham, AL. They've got about 20 Shorty buses listed and about 4 IH 65 passenger buses listed. They're a big auction house out of south Mississippi, and the buses usually go cheap ($400 - 1500).
There's no pictures of them, but VIN numbers are listed.
The construction equipment looks like it's from Jefferson County, AL. No idea where the buses are from.
Might be worth checking into if you're wanting an International/Blue Bird conventional!
