Adam, are those the only lanes where you live? 'Cause if you just want to practice, any bowling center should do. I understand you might want to practice at the same center you bowl your league, but it might be better to pracitce on different lanes and since the lanes might be different(running, tight). I don't have any problem finding lanes to practice on, since most of the houses have at least 24 lanes. I know it's not the same, but practice at home. Practice you delivery in front of a mirror making sure that your square and solid at delivery. Use visualization, and picture yourself making good shots. These practice techniques will not replace actual practicing on the lanes, but they so work. You want to get a good mental picture of your delivery and shot. Having a good mental game goes a long way.
