There is garbage everywhere and something gross (maybe garbage, maybe something toxic) in the big blue slide at the park on Front & Lewis St. I've noticed more teens there lately who may (or may not) have vandalized the park with garbage by rolling the can down the hill. I've also seen teens abusing the park equipment and throwing large rocks at each other when little children are around. I politely asked the kids to please stop throwing stuff, but they ignored me. Maybe more police presence will help this.
