Wait a tick...BikerCelt (check spelling)... plays with the Fort Vancouver group? They played at Kelso, I even chatted with a couple, because I was curious if the tartan they were wearing was indeed the WA state tartan (and it was... I had only seen it in pictures on the web before... it's pretty snazz).
There were supposed to be a couple other guys there (from the yahoo group, one of which I think is an Xmarker), but I didn't keep that sharp of an eye out. Saw a lot of kilts there, but it was the highland festival, so that doesn't quite count.
Still the only person in Federal Way to run around kilted as far as I know.
