My thanks also goes out to the volunteers. Unfortunately, calling the litterbugs pigs (pigs are cleaner) probably won't improve the problem since they are tourists who won't be visiting this website. I'd go for a more public approach like what that Party Supply store did for shoplifters. Let's get people to snap pix of litterbugs and their litter, then post it for the next big weekend event and ask for tipsters to ID the litterbugs. Just my $.02.
