Eh...as a resident of Ohio I'm going to play devil's advocate. Yeah, this should be silly legislation that never sees the light of day. It is silly legislation, no doubt. That said, the rivalry and hatred between the two states is very real. It goes beyond the football field, it's existed since before Michigan became a state. It's more heated than the Oklahoma/Texas rivalry by quite a bit imo. There's bad blood that goes back generations. What I'm getting at is these two don't need any reason for a fight, they're always ready to go at each other's throats. Something as silly as a flag planting is enough to draw blood with them. You can better believe next season when they're playing in Ann Arbor there's a strong chance OSU will be out for blood and they'll be looking for revenge, and we'll see another flag planting. Then you'll see a return trip in Columbus, etc, etc. It's stupid, but that's how those two teams operate.
It's unfathomable, but that's because our team has more class than either of those programs. In 2005 Michigan State won a close one in South Bend, which ended up being Weis' first loss. They planted their flag on our field after the game. The next season in the "Hurricane Katrina" game we returned the favor in a late comeback...and a trio of Michigan State players stood in the center of their field at the 50 yard line, ready to defend their territory. No Irish players came to plant a flag. It was a pretty pathetic sight.
So, while the legislation is pretty silly, it also prevents a possible catalyst for future fights that will certainly occur between the two idiots. Also, to continue playing devil's advocate, there are a number of Ohio laws that are way worse than this one already. I'm still a little ticked that it's illegal to hunt whales in Ohio on a Sunday!
