Went bowling… the facility tracks the speed of your bowling ball (guess I spent my years at older alley’s)… I found myself watching the speed results more than the score. Instead of being concerned about the lane conditions and placement of the ball; I kept thinking (can I get it up to 20!)… then I threw my arm out. I can see how this added information can be helpful… I just bowled for 50 years without knowing it. The screen animations also showed suggested placements of the ball to pick-up spares… and people seem to be bringing more balls to select from. I recall when I moved up to two (dry lanes/wet lane) and considered a ball just for spares (which would bring my total up to four) and stopped… having a great score every game just did not mean that much to me… I decided I could be happy with my two balls.
