Good luck on your April 4 swap! If its like any of the others, and the feild of dreams, they will come!
Just hang in there, if its like so many others, word of mouth after that first one, it will explode- look at Milford, NH for example. You was at the first one, which wasn't much but a good turn out at the same time, and its grown.
So even if the BYC group doesn't keep up with this, the locals will in that area.
I'm putting up flyers in 4 towns, especially feed and lumber stores!
Good luck to you all and most importantly, have fun!
