I grew up in Texas. "Don't mess with Texas" will forever be burned into my brain. You'll get people yelling at your face if anybody sees you just dump trash on the ground where I came from.
When I moved to California, I was shocked at all the litter. People out here don't give a crap.
The grass is greener on the other side no matter how many times you cross the hilltop. I've had the pleasure of moving out of Texas twice, but I fear I won't live long enough to experience that thrill again. I saw plenty of trash on the roads in Texas... broken glass, dead animals, nuts, bolts & screws.
We're more crowded here. And we have a lot more tourists who are hostile to our politics, our taxes, our yoga, etc. The Arizonans and Texans trash Carlsbad every summer. It's happening right now. If you want to live in Paradise, you have to put up with the crowds. I'm proud of my town, and I spend a fair amount of time picking up trash & dog poo.
And to the OP: Amazing how angelic we become when we know the Whole World is watching our every move (or when we're expressing ourselves on internet forums.)
