Lol, apparently I wasn't the only one who couldn't find any info. It's been a while since I've done a H/J show, but it seemed a tad pricey. Would have been at $75 just to go around a hunter course one time. Is that typical or are there some less expensive outings in the area?
Sport Horse Inc is in zionsville and has a very well run set of IHJA and "novice" schooling shows that are reasonably priced. There are two rings, a derby course, and they really go all out on the decorations of the fences. It's been a few years since I've done one but I enjoyed myself there.
Here's an entry form for their Novice set of shows, It's $15 a class for hunters, $20 for jumpers or derby classes, $35 for a stall or tie to your trailer, and $10 office fee.
