Currently, the only Tartan I wear is the USMC Leatherneck. That's what I consider my "Clan". I do, however, wear a saffron from time to time in recognition of my Irish heritage. I also wear my UK on a regular basis. I'm considering, however, getting a kilt in the MacAlpine Tartan as that's the oldest link I've found in my family tree... Maybe if I win the raffle...
