I wonder how many times a bowler has strung 35 in row. Either front or back. 

Guy I used to bowl with subbed one night n Arizona when he was there for family holidays, lefty, stoned an 8, ran the back 35 for 890.  They flipped the pinsetters back on to see how far he could take the string, and bowled another 4 before stoning another 8 pin.
