10. Littering: It amazes me that guests litter when there is a trash can, literally at least 30 steps from anywhere you may be standing. I don’t understand why people think it is OK to leave or drop trash, or think that it really takes that much effort to just throw it away and keep the parks clean (and safe, since litter can cause people to slip, fall, get stuck in strollers, etc.). It takes a few seconds to throw your trash away and we would all greatly appreciate it if you did. No one should have to pick up after you!
