Shelter fit for a party

Cascades Gateway City Park in Salem has a few shelters like this one but I found them to be a bit boring for a photo-op so after experimenting with Photoshop a bit I came up with this. Now this is a party in the making. I wonder if the city would be upset if I painted the shelter to look like this for an upcoming family barbeque? (Alright, you can relax Salem. I don't even own a paintbrush!)
