I can totally see that happening. In my Friday Night league a couple of years ago (Cactus Bowl in Tucson, AZ). On the pair we were bowling on that night, we noticed on one lane that the ball was catching air just prior to hitting the pin deck. Fortunately for me, I was able to play away from that spot, but the next day they had a JBT tournament that one of the kids that was in the youth league that I coached in ended up on the same pair and it was still there. We went and talked to the owner and after the tournment, I walked down the gutter with him and saw that one of the panels on the lane had been warped which was creating a ramp. This happened between the last panel and the pin deck, so the ball could catch enough air to go that high, but if it was one panel earlier, it definitely would.
