This tanker jackknifed then went through the guardrail in the median on rt 93 near Boston. I was not at this scene i was too young at the time.
Equipment used Ford F-600 with Holmes 600, 1969 Autocar with Holmes 750 and the other unit was a 1982 F-350 with a Hubbard back.
i found this pic and had to post this. Thanks for looking. Chris
