Be as it may, the park managers do not want to actively facilitate littering. They keep a fence in place knowing some will litter anyway, but at least they are not enabling it. After all, a park should be kept clean for people to enjoy it - that’s what parks were created for - to relax, and unwind for some peace, in a clean environment. Disrespectful people may still use the park in inappropriate ways, but the manager is not out there helping them do those things. Where before you might look at the park and see a fence and decide - meh, not gonna bother, now it’s wide open so you can litter even just by driving by, rolling the window down and throwing something out without a care. A fence keeps out the bulk of the littering. I hate this analogy and the fact that I’m using it 🤣
