In addition to the comments mentioned above, I would like to add a few thoughts.
In the past 20 years, 5 different houses have closed up in my county. With the economy as bad as it is, I really would not be surprised if a couple more shut down in the next 20. Same thing for the stand alone pro shops too. There are only a couple shops operating in the area that aren't part of a bowling center. With the decline of active bowlers and the rising costs of running a business, the independent pro shops are really struggling to survive.
The pro tour as it is today is a mess to say the least! You see a lot of the same people week after week. ESPN needs to quit recording shows ahead of time and then showing them well after the tourny has been over for a while. In this day and age of modern technology we already know who won and what ball they were throwing when they won it. Where did the live telecasts go? And who is doing the schedule? Remember when the tour was a real tour that went all over the country and not just a showcase for some place in Nevada? If this trend continues, the pro tour won't be around in 20 years or even 10 for that matter!
In the next 20 years, the bowling ball companies will still continue to do their usual thing. Every few seasons they will produce a new and "revolutionary" ball that will drive up averages a few more pins and give the average bowler a better chance of scoring higher. I really don't have an issue with this as long as the bowling centers change the oil patterns to match the changes and keep the shot competitive for us. I hate to say it but I think we will see more balls produced outside of the U.S. due to rising production costs. I am a Storm / Roto guy and I hope they keep production in Utah for a very long time.
I have been bowling for the past 35 years and I plan on bowling for at least 35 more. As much as the game has changed and as much as I complain, it still is as much fun for me now as it was then. I still love the competition with other bowlers like me. I enjoy meeting my friends every week and forgetting about work and other streesful things for a few hours. In the end we are all reading this and complaing for the same reason.
It's because we still love the game.
