The crowding at mat side you will see a lot. you just learn to deal with it. We have been wrestling for about eight years and it hasnt gotten much better. There are some tournaments that really enforce it, but there are some that just really dont. the only thing you can do is ask them people nicely to take a knee and 99% of the time they will or they will move. It just all in how you ask. Nice word will get you a long way. Just remember that.
