Actually, I was reading Frayed Laces latest post and she had a great idea: A race shirt exchange. Frayed explains it better than I could, so I'm going to paraphrase:
The whole idea is that if you run a race you had done in prior years, you send your race shirt to your running buddy across the country, and vice-versa. There is a discussion on this in the forums of Steve Runner's Phedippidations website as well. A site that runners should all visit at least once. Oh, and RazZDoodle is my running idol.
I have one race t-shirt that I can part with and it hasn't even been worn. I'll keep the 500 miler t-shirt. It has a mind of it's own. It almost ate the dog. Long story.
Give me a shout if you're interested and, if you are, post something about it and keep this alive!
