There are several on Facebook..... but be prepared for eleventy billion 14 year olds to tell you you're doing it wrong, LA200 cures everything, they get 100% reception rates, and sell every calf for $4,500 at 2 months old.

Steerplanet has some really good info buried in its history and some very experienced people that still browse it.  Seems like most people just lurk and rarely post anymore though.
