I'm currently collecting tumbleweeds. I'd say I need about five more. If you want to be a total creep...drive 5mph and chase a tumbleweed bouncing down a remote South Dakota road at dusk. Do not notice the lone female jogger ahead of it until many minutes later when she looks at you and you see the panic in her face. Don't try to explain you were chasing a tumbleweed-that's stupid and suspicious, even if it's the truth. Just turn around and drive away. I'm speaking from experience. Next time I'm chasing one, let's hope this playing somewhere in the background.
