OK … heres my two cents.
First of all, Ledges is about an hour away for me. St. Louis is 5-6 in GOOD driving conditions, I have heard stories about it being a 12 hour drive in icky weather. (PASS!!!)
Second of all, I prefer the footing at Ledges. The indoor is re-graded every fall and fresh and ready for the winter season. The footing at STL was hard and packed into their feet and had them walking on big clumps of dirt. (PASS)
Third of all, Ledges traffic is pretty predictable. Friday nights?? NOT greenbean time. Sat/Sun during pony divisions NOT greanbean friendly. Thurs/Fri during baby greens and all pro divisions? Not so bad. Have one you want in a quiet ring? Be on 10 mins before the show starts, and go in the ring first(assuming it does baby green)… I would bet a pretty penny you will be in the schooling ring with maybe one other horse. In the mornings if you need to school, come early… don’t wait till the mad rush at the end of schooling time.
At ledges you can jump everything in the morning which i liked for my green horses. Even with the upstairs balcony, I find my horses are far less spooky that those silly aluminum bleachers at STL. The bleachers combined with the footing packed in your horses feet flying out of the ring can really send a young one flying. It can sound like gunfire when those dirt clumps hit the bleachers.
Ledges jumps are prettier, concession food is delicious, Ann Hubbards right there at the show, the office staff is friendly, the management has always been OVERLY accommodating to me. Even to the point of staying late on a sunday to allow me the jump one around that had a meltdown with a kid…
Overall, yes the schooling area has traffic, but its easy to predict when it will be quiet and when it won’t. I find it hard to rationalize the drive to STL unless you are going for a Prix or something.
