I'm one of the new park host's there, I brought it up with Russ, he deals with youth services, parks and rec, etc. City knows how slippery it is and has been trying out different companies for painting over the graffiti. They're trying to find a company who's paint isnt too slippery but I guess they still haven't found a decent one yet. I'll try to keep the bowl as dust free as I can, I guess thats all I can do for now.
no paint at all would be the solution
