MI 2 AZ glad to hear that you were ok! As a CFR-D with the Fire Dept I have responded to many calls at the local lanes, mostly for falls, and those were on the approaches and some out onto the lanes. Most were "lucky" with only some bruises and bruised egos.
BUT, we had many broken bones, and cases where the person did hit there head. Also a few heart attacks.
I still believe everyone should learn CPR and the Heimlich, and those involved in youth sports, some good solid first aid.
