I'd like to argue for more netting -- because deep down I believe anything that keeps people safer -- adults, kids, the handicapped, the "chemically impaired," whatever -- is a good thing.

But I also have to say, even though I'm not a sports fan (wow, is that an understatement!!) I can see how netting serious enough to really make a difference would degrade the whole excitement / visual experience of attending a live game.

In my imagination I see a section in the center -- really good seats, with no netting -- and netting sections on either side for those who either don't care or prefer that. That might not be a good solution -- and it might cause other problems, etc. It's at least an option to consider.

Were I the one in charge of this decision, I might want to try that for a season to see how it worked. Then either leave it as is, fill in the open section with netting, or take the whole thing down and scrap it. (Yeah, I know. The expense, the expense. I try to ignore that whenever possible. I opt for the best solution. Not necessarily the cheapest.)
