Leaves!

Leaf crunching is by far one of the most enjoyable activities known to man. Don't you love the satisfaction of stepping on a particularly crunchy one? It's basically a natural high. Right now is prime leaf-crunching time, so be sure to keep your eyes peeled for the fallen foliage!

Also, it's important to remember to avoid letting feelings of shame enter your mind as you walk down the street, crunching away. Sometimes it's easy to feel kind of ridiculous going out of your way to step on that extra crunchy one (you know, the whole stutter-step thing), but just go for it. Everyone else is secretly wishing they were doing the exact same thing.
