Why when people state THEIR opinion about a track, cost, operation or anything about a track every promoter get so butt hurt? It is their opinion, and they have a right to it.
I learned a long time ago when I first got into politics, everyone has an opinion. They may not agree with you but they still have their opinion. Just like a politician, you're probably better off reading those opinions possibly learning something from those opinions but never responding to them. It'll be a lot less stressful for you. And at the end of the day you may learn something about your event or organization.
