funny post.
I call it "going fishing". I see the other rider up ahead and I reel him in. Just like a fish you don't want to pull too hard or move too fast or you'll lose him. Nice and steady. Take the time to watch him. How he rides. Is he jumpy? Steady and strong?
Hunter instinct.
And once you make your jump you've got to have the guts to stay with it or you're toast.
And I've met some of my best friends this way.
