I don't know, a lot of adjectives come to mind, but cool isn't one of them! And yeah, having fake palm trees next to real trees is kind of funny, almost as if the Mets had a big apple tree right next to the pop-up one.
If anything, it's "anti-cool" or "post-cool", like being kitschy for kitschy's sake. I'm afraid it may be a point of derision, with teammates pointing to it from the dugout when a HR is it, endless goofs on it on MLB Network and SportsCenter, etc. I guess we'll see.
Either way, with that and the fluorescent colors, Toto, I've a feeling we're not in Kansas any more.
