Seed Round Robin
I came across an interesting thread in the Seed Exchange forum. The thread is for a seed round robin. A box/packet of seeds is sent around to a list of those interested. You just replace as many seeds as you take out of the box, hopefully with different seeds. The travels of the packet is tracked on the forum. In fact, there is now a new Round Robin forum they are using to track their 2 seed boxes. That round robin is already closed, but I thought if enough people were interested it might be fun to have our own Okie seed round robin.
