One rumor was that Jimmy departed southeastern Michigan in a Gateway Transportation trailer, inside a 55 gallon drum.
I once read that he was transported to NJ. on a Gateway Line Haul. Weren't they in Jersey City on Tonnelle Av.
I see mud beat me to it. Yup, that was the rumor going round.
Maislin bought Gateway in 1979. I would assume they interacted before the actual purchase was completed. We didn't ask too many questions in my local at that time. That was frowned upon. You might be correct about their terminal SF, I really can't remember much about them till we (Maislin) bought them. I tried to grab Gateway tractors in Kearny as often as I could - they had A/C where ours didn't.
