We bought some small round pens there a few years ago and a training cart. That would be the only thing that I would be interested in is another round pen, we do not sell or buy horses at auction sites unless of course its the "Taylors Pony Farm" or other well known breeders own sale.
I imagine that there would be some buys of horses there going to happen but I aways found that you get what you pay for and sometimes you do find special one that you have in your barn at a bargain price. JMO
Some people need the money and cutting back before winter arrives so they are taking all types of livestock to area auctions at the moment so they are probably going to go really cheap unless alot of people are interested in the same animal going for bid.
The VIP auction this spring we heard had some really nice quality horses there but I do not know if they are going to have it next year or not.
Was there a Tri-State miniature horse/tack auction this October? Didn't hear of anything there going on either, but they usually have a good sale with colorful miniatures there too that the club puts on.
