Back to bowling

My kids enjoy bowling and have been on bowling leagues in the past. We signed back up to be on bowling leagues for the fall. They have their own balls and it is cool in the building, also doesn't take up a lot of time. We started the new league today. Kyle has normally bowled with bumpers and just throws his ball down the alley. He tried no bumpers the other day when we bowled for fun and did fairly well. He tried with no bumpers again today. He also tried a different ball (one that belongs to the bowling alley) and used the finger holes. He did really good and did not get frustrated. So I took his ball in the pro shop and the guy is going to drill the holes, it should be ready next week when we come to bowl.
