I'll see if I can borrow a camera sometime soon. I'm actually surrounded by
video gear at my job (I'm a broadcast engineer), but taking it down to the bowling alley for personal use would be frowned upon.
Regarding my stride: I measured again and my natural
brisk walking stride is more like 10 feet for four steps. The ~9 foot figure is for a lazy stride. Maybe I just need to line up my
heels to the 12 ft. approach dots. I'll be going to the lanes at lunchtime today for some practice. I'll give it a try.
Question: are the dots on the approach
always located at 12 and 15 feet from the foul line, or is this variable from house to house?
