I have a 1940 Ford trailer that I pull behind my Trike. I am going to Trike Talk Rally in Maggie Valley. I want to pull my trailer up there but I haven't decided how do I take the trailer off of Trike when I get there and lock it up so that no one steals it. I have seen chains but that seems like a lot of weight and that is expensive. I have seen people lock a cable around a telephone pole. Sure takes a lot of cable. How do you do it??
