Your closest would be the CORPS show Richmond, which was held in past years.
Unfortunately, this past year was their last show. The show may be hosted by nearby Sutliff, but that is just a rumor.
You might want to drive up to Winchester the first Tuesday of the month for the Winchester Pipe Club. (at the JB Hayes shop). If you can make it, please let me know and I'll be sure to attend (I can't make every meeting).
