I don't really care about the whole thing but I agree with Team327. Who's going to see them? It's just going to look like a colored patch to everyone else.

And maybe I'm missing something but how is showing Spiderman ads in new and funky ways (that you can't see) supposed to bring a younger audience to the ballpark? If anything, they should show baseball stuff during the Spiderman movie or during kiddie shows, not the other way around.
