Many of the members are from here on BYC as well so you would recognize many of them. So many use the same screen names. These sites are set up similar to BYC with forums for different needs, even a Random Ramblings forum.
A question will be posted like, "What year was BYC or Back Yard Herds first started".... and you have to dig around the forums here or on the sister sites to find the answer. :p
