Well, nothing really. I like the security gained in just having a stash pocket available. Just in case I ever need to stash something. I think it might be fun to stash stuff like my key to my lock or a twinkie or something. Then you'll see me on "Cops" saying. "Dude, I don't know nothing about that Twinkie. I've never seen that Twinkie before in my life! Man, I'm just borrowing this bag I don't know nothing 'bout no damn Twinkies!" and then I'll try to run only to be nabbed by a donut eating cop because I can't run in spd's.
