I guess I'm lucky in that we had great junior leagues growing up with top competition week in and week out. I stayed a junior until I was 22 (I was still 21 on Aug. 1 so I could bowl another year) and enjoyed it very much.
However, if you are one of the top juniors at your house and you're are still bowling leagues with 5 year olds, then you either need to find a different house with better junior competition (if there is one around you) or turn adult. You need to challenge yourself with better competition on a week-in, week-out basis if you want to improve. Bowling the occasional high-end junior scratch tournament won't do that for you.
That's ridiculous about not oiling the lanes for you. Dang, we always had the fresh, just-layed-down Saturday morning shot and it was often a challenge to get the ball to wrinkle! I think if you found a better junior league in your area (if one exists) you'll find that the lanes are oiled more often for you. I suspect that your house doesn't oil now because most of the bowlers are bumper-bowler types who don't really need any oil.

You weren't unlucky when you left that corner pin, so shut up about it already!!
