Ive only been riding for a few weeks and I sure got tested in my reaction time and skills this morning. Doing 80 on James Ruse Drive behind a truck go to overtake and as I pop over to the right lane there are three huge industrial "things" (no idea what they were just that they looked heavy and painful) basketball sized bouncing along my new lane heading straight for me. I'm blocked by a barrier on my right and the truck I just passed on my left so no changing lanes for me. Lean left then right dodging these "things" and as they got close I lose sight of them and only prayed that I got through without getting clipped. Doing slalom through 3 objects in like a staggered formation (I think somebody wanted to truly test me) at 90kph is very very unnerving. And I had no idea where they came from, the truck I passed couldn't of dropped it... Can divine intervention try to kill you as well save you because I swear they were aiming from me and just materialised out of nowhere.
