This is exactly how things get ruined for everyone.  Ever wonder why you can't go hang out in nature at night, even though you don't want to start a fire or leave trash behind?  It's because horrible little brats like this came before you and made such a mess that now everything is off limits, has to be routinely patrolled, and ends up becoming private property because it simply costs the city or state too damn much to keep cleaning up after these types of people.  They spoil it for everyone else who simply wants to enjoy nature and leave only footprints in their wake.

Ex Output:

Yes
