The most recent patch I have is for the Beast of the East ride in 1993, after that most events started giving out t-shirts. One reason I miss the patches is that they were very easy to store or display, now I have two drawers filled with t-shirts from the various rides over the years. Eventually I'll send them to one of these people who can cut up the shirts and make a nice quilt with them, then I'll just have to figure out where to hang the quilt
