I still think it's a cop out to not expose some of these tactics to help some of us who don't deal with cattle for a living and will probably never ever go to a "ranch meeting."
We had a similiar thread to this in another horse forum, and folks were very forthcoming with their stories and warnings/tips to be aware of.
One of the main things I remember about buying a horse is to try and show up anounced to check out the animal, as it seems some guys will drug a horse to make it appear friendlier / calmer than it naturally is. If you always call before going out there, it gives the seller time to do whatever he needs to do to the animal.
As far as the cashiers check scam, it's been passed around here for quite awhile, but for some of the newcomers to the forum, here it goes....
A buyer offers you your requested price for your cows, sometimes even a little bit more for your trouble. He says he only has a cashiers check from his bank in a certain amount, usually several thousand dollars over your selling price. He says he'll send you the entire check, and you can take out the selling price plus any shipping charges you think will apply, and then send him the remainder or give the remainder to his driver when he picks up your cattle. This is usually pulled on late Friday or Sat, since the banks will be closed. So now he has your cattle, your money back from the cashiers check, and he is long gone. When you go to the bank Monday morning, you find out the check was a fake and you just lost everything. I know this sounds farfetched to most people, but people get ripped off everyday with far sillier schemes. We hear on the news every few weeks where some older guy fell for the lottery scam. Same thing, fake ticket, they will be deported if they turn it in, they sell it to the old guy for 1/2 its value. Guy goes to collect money from lottery office, finds out it's a fake ticket.
