I was behind
this bus as it was being towed down Rt. 128 to Rt. 9. And I was like holy crap, that bus EXPLODED. I hope no one was hurt! (...And I wonder if I'll see this on the news when I get home!)
A police cruiser was driving slowly behind the bus, for safety. The door of the bus was hanging open. At the exit to Rt. 9, they stopped on the ramp, and the driver got out and shut the door. Then they got onto Rt. 9 and I was able to (slowly, carefully) pass. I recognized the towing company (they're based near my house). They took the turn off to the towing company and I drove off to my next student's house.
So, a bus caught fire. Good news: No one was hurt.
