Hi Joel,
      I might be interested, what would you like to trade?? I have
quite a few boards and other pieces laying around, send me a want list
and I will see what I can do for you. I might also consider just buying
it outright from you, let me know what works best for you. Just
curious, you mentioned Hamfest in Dayton, I live in Springfield, OH, not
far away, just curious where you are.

                        Thanks
