A local chiroprator appearantly got tired of loosing his trailers and came up with a way to put a stop to that. He founded a company called Verticle Lures. One of their main products is a hopped up jig and a trailer held on by a locking device. So far the company is doing well. I read he turned a modest profit the first year in the middle of rapid expansion. My feelings....People will by anything that LOOKS impressive.
