I think the USEF allowing shows to happen in June is your bigger issue. Reporting a facility for holding an event so that you and your friends are ensured a venue for next month seems rather petty. I’m dumbfounded by this tactic. So odd.
As if the local authorities would not have been aware of it anyway? It’s not like GSWEC is tucked away in a remote corner of the area where no one would notice. Also, consider who owns that facility. I sincerely doubt legal counsel wasn’t consulted in this decision. I don’t have a lot of faith that this “shutdown” will be fully executed.
FWIW, I am in Houston but not attending. My barn isn’t going but even if they were, no way would I pay A show prices for a schooling show. Nor do I feel like all the rules make it sound like it will be any fun at all, as @inca pointed out above. But I would never begrudge those who made a choice to go for their own personal or financial reasons. That’s just weird.
