PA land trusts

A few weeks ago, I found an internet site of an org. that 
matches Pennsylvania farmers that wish to sell with those who 
wish to buy farms. Now,I  can no longer find that site. Does 
anyone know of this group, and can you give me info on how to 
contact them?
Any help is appreciated
Thanks DC
