I two down everyone... well except those trike guys... I three down them, most times it confuses them....
I realized how "ingrained" two down was into my brain yesterday while riding in my truck.
Window down arm on door, hand hanging out and down (its a country thing), I spot two bikes (look like HDs but not sure), so as they pass me on the left, I give'm the ol' duces out my truck window.
They didn't give'm back to me.... whaaa??? assho..... oh... i'm in my truck... sigh....
