... please ask them to not put permanent stickers on all the lamp posts and other metal surfaces in Hamilton Park.

I understand fliers, magnets, etc advertising your company, but stickers that just don't come off is more like vandalism. I've noticed several people trying to pull them off without much luck.

I'll try sending them an email too. Just would like to keep the park looking nice.
