About a month ago we had our local association/city tournament.  At the end of day one the lane machine broke down, so things were delayed for a week until parts could be had to fix it.  Since then the right side has been a nightmare.  An unbelievable number of corner pins, pocket 7-10's, weak 5 pins etc.  Finally, 2 days ago, someone had the bright idea to check the lanes for oil, i.e., to produce a lane graph.  Everything was perfect - except for the 60 units that went 35 feet up the 10 board.  One hopes it will be fixed soon, but what a nightmare it has been.
