Dude, you are in Medina Co. They have their heads way up their butts. You may wanna try taking to the guy who vends ribs off 42 in Medina right across from the Wal-Greens. He isn't mobile but cooks out of what looks to be a 55 gal drum. I still visit Medina quite a bit, and haven't seen any vendors that do sandwich trucks or trailers. Last one I remember in Brunswick was Buddy's Auctions.
I am orignally from Medina, so once you get it cooking let me know!
