Is there any interest in something like this? I'd post in the exchange, but there hasn't been any activity there in years!
This forum doesn't appear to e very active. I have tried getting a spring plant swap going in york county for the past couple of years. There is a great swap that I go to every year in New Hampshire. It is happening the first sunday in June at 10 am. It is always a great swap great plants and great people. we have a pot luck afterwards for lunch check out the New England Forum for details
