Not quite sure HOW this works (and since it's a Windoze app, I'm not likely to try it) but there's now a smart-phone app' that allows one to align your front wheels! It's only 99¢- will someone on either side of this discussion spend a buck and tell us how this works? +- 19 ft, yes, but I can't believe the level of accuracy the app' implies.... J DeRyke
