We are having several table practices during our regular wrestling practice for our parents and volunteers to get familiar with all of the jobs at the table. We use live wrestling and the coaches ref the matches. Experienced table workers train and oversee any questions or clarifications.
I've watched parents begin the practice not knowing what to do in the beginning and teaching others by the time we were done. Parents new to wrestling also learn the calls and have a better understanding of what is going on while their kid wrestles. They also see first hand how chaotic the tables can be and have a new found appreciation for giving respectable distance from the mats.
I also agree that if there was more control over who is allowed at the mat, spectators would not have a need to move closer to see their wrestlers match.
Being nice and having respect for each other is another point I agree with and sets an example to the younger generations.
Satellite weigh-ins are a big help in starting on-time. As parents, we take advantage of them every time so our wrestler can get a nights sleep and eat properly vs. worrying about weight in the morning. (helps if you don't cut it close to the weight too :))
Thanks for starting this chat and great suggestions! We all know what we dislike, but communicating solutions is what helps us achieve better results.
