I have vanity plated on my trike, so tags were not an option. I have a 2001 ultra trike. On the bike I have a windshield bag, for glassed and gloves, and things of that nature. What we did was to take my blue card and have it laminated. We used Office Depot for that. They offer different weight laminates for different jobs. I chose the heaviest one that was offered. Trimmed it down with an edge on the side. Left a tab on there, punched a hole in it and placed it between the windshield bag and the windshield. The center bolt of the windshield goes through the hole in the tab of your plate and holds it into place. If someone wants it, there going to get it. Trick is to make them work for it. Since they are thieves anyway, and therefor inherently lazy, they will not work to steal yours, and will move on to an easier target.
