While I've never been there, a hear that the course is very technical. A lot of horse and rider pairs have problems with technicality down there because it is described as a "moderate course- with pairs with some experience at that level". Some go there as their first move up or when they aren't actually ready, and that's when you see the most mishaps. It's a very "looky" course and some horses are just wary of it. www.poplarplacefarm.com
is their website if you would like to take a look at what the jumps actually look like.
Stormy, I think you'd be fine at BN. Especially on Geof
