Looked At It In 3 Dimensions?

I think you are wrong. It only appears to cross on a 2 dimensional representation. In three dimensions I don't think Pluto's is ever within 1 AU of Neptune's orbit. Not sure of the actual distance, but I remember shock at seeing how far apart the orbits were when represented in three dimensions and thinking "hey their orbits don't actually cross". Would have thought geologists think in 3 dimensions.
