If you have ever helped set up a 3D course for a tournament, you will get this analogy all too well.
It doesn't matter how hard you try, you absolutely can't make everyone happy. It's going to be too hard, or too easy. The shots will be too long, or too close. Too brushy, or too wide open. Too many deer targets, or not enough deer targets. Too many big targets, too many small targets, too hot, too cold, too wet, too dry, too hilly, too flat...it just seems that some people aren't happy unless they are unhappy.
The kicker is that normally the ones that complain the most contribute the least. You won't catch them volunteering to help set targets, clear lanes, put out shooting stakes, work registration, build trophies...but they will dang sure put in overtime when it comes to complaining about something. If it were up to them to actually do the work, there would never be a tournament to begin with...but they sure won't hesitate to tell you how you should be doing it, and point out everything they think you are doing wrong.
You finally quit trying to cater to every squeaky wheel and just do the best you know how to do. Legitimate criticism by people who genuinely want to help make it better will always be welcome, but the rest just aggravates.
My two cents.
