You're right, I was venturing into the absurd to lament about the legalI don't know about this one. I think it's a stretch to compare a kid getting hurt by a batted ball vs. field conditions. I do NOT disagree that it would open a big can of worms. And let me be clear, I'm not advocating for a lawsuit of any kind against anyone. We have too many frivolous law suits clogging up the court system already.
That said, I do wish more people pushed more tourney directors to do a better job of field maintenance. Take some pride in your tournament and if you truly love and respect the game then show it by giving the kids a safe and fair place to play ball. So what if you charge an extra $1 for cost of admission, most people would gladly pay that if they knew it was going towards something like field maintenance. Again, I'm not suggesting someone do the work of running or hosting a tournament without making some money. But your tournament will get great feedback and word of mouth will spread quickly about tournaments that do a better job than others. The small investment it would take to hire some high schoolers or college kids to make minor improvements between games will pay dividends when more teams will want to enter and your tournament will grow as a result. But this is all just one man's opinion. People who don't have pitchers for their DD might think I'm making a mountain out of a molehill.
I agree about the field maintenance, part of the volunteer recruitment at the small tourney I run is parents to do two hour shifts of raking, chalking, and grooming between games as time allows. We don't have the best facilities, but we do have some pride in presenting the best we can with what we've got.
