This auction has a very large Amish influence, so there may be nothing online about it.
The variety of tack was pretty good.. A very large percent of it was driving harnesses, but they had a good amount of western tack and a small amount of english and even smaller amount of austrialian tack.
A lot of the tack sold at auction is brought in day of and tagged day of (even minutes before it goes on the block. Heck some items went on the block were sold and then tagged. lol) so there is no telling what exactly is going to be sold untill you are there.
But there are groups that come in and sell in booths, that have items that are set at a price. The prices do range, but I've never noticed anything that was way overpriced. And even if you do buy from a booth I'm sure you can negotiate the price a bit. Most of the stuff at the booths are new items, most of the stuff on the auction block are used items (except for their bulk items like leads and saddle pads, etc.), but it does vary.
The horses sold at auction are always a surprise too, they usually have a large group that sign up before the auction. But all the years I've gone, there have been trailers of horses that were brought in and tagged minutes or hours before they were sold. I have my info sheets with the horses that came through, and 150 horses came through friday night (they started at 6pm on horses after all the tack was sold) and 722 horses came through on Saturday (they started selling at 9am and sell till they are done, it isn't unheard of them staying untill midnight still selling horses). And those were only the horses listed that they compiled on Friday, there were a large number of horses that were sold that were not listed.
And on the first day of the sale they sell an amazingly huge amount of items that come in day of and are sold at auction by way of golfcart (well multiple golf carts) and loud speakers driving up and down the rows until everything is sold. This includes farm equipment, tack, junk, household items, homemade items, etc. It is a crazy house the first time you see it. Think Outdoor Fleamarket (the size of 1-2 football feilds) and every item is auctioned and sold.
My family has gone a few years just for the event of it. It really is something! lol My mom and I just have one suggestion and that would be.... have a ho-down/dance on friday night in the arena. LOL We think that would make the experiance complete.
