Schooling/rules question - unrecognized horse trial at rec event site
We have a recognized event coming up in our area. The week prior to the recognized event, a pony club is having two unrecignized one day horse trials back to back at the same site.
The omnibus for the recognized event says the cross country course is closed to schooling well prior to the date of the pony club horse trials.
My question is would someone planning to enter the recognized event be allowed to enter the horse trials or would that put them in violation of the rules for the recognized event? I'm guessing the latter, but it's not addressed specficially in the information provided for either the event or the horse trials.
