Nailing

That's a lotta nailin' ol' timer. Could hear you puffin as you switched to the double fist technique. Still impressive that you got through the row without banging the shizz out of the decking.
Shoulda video'd a 3 or 4 way wizzasted hammer shesh, where Larry has the Estwing axe swingin wildly past our ears.

Shoulda seen it - I finished all 36 of them, but the memory card ran out. The left-hand-power / right-hand-aim technique works great as therapy for my busted azz left wrist.
