A multi-car collision had occurred at a considerable speed. (sadly a driver had lost a life in this accident) this collision entailed a very large commercial truck being hit head on, by a vehicle traveling in the opposite direction.( this 2nd vehicle being a van) after this severe impact with the large commercial vehicle, (which created heavy damage to this vehicle, removing the front axle) the van proceeded being ricochet off the large commercial vehicle, around it, back into my oncoming lane.

Within 3 days, I had a sidewall puncture on one tire while driving on our ranch. The tire had to be replaced. Now, just yesterday, sep. 15, I had another sidewall puncture while driving on the ranch. I just left the local discount tire, where they are waiting for a new tire to arrive so they can replace the old tire.
