I think that's what they're talking about under the post called "Kay's Swap" ( a little further down this same page).

No there was suppose to be one up there too. Kaye's swap was south of Fort Smith.

Well, actually I found my own answer by accident while doing a semi related google search. It's in the forums on Dave's Garden. Apparently it went really well.

I posted about it on the conversation forum in the plant exchange. It WAS a lot of fun and now I think I'm hooked on swaps. There was so many plants I didn't know where to start. And even though I didn't have much to trade, I went home with so much more than I brought. Everyoen was nice. There were two guest speakers. One was a Master Gardener who told us about the program. The other was a supervisor for a cancer group that paid for Nancy's surgery this spring. And they honored the nurse who worked so hard to get the funding for Nancy. The ceremony was touching because nancy stated that the nurse saved her life.

Nancy planned three days of events and everyone had a wonderful time. I'm still trying to finish planting the stuff I got. And then nancy said I could come and dig some more at her house too. So I better hurry and make some more beds.
