Thank you all very much for your answers. I've reviewed the oral arguments and read a few of the briefs. Not having any legal training, other than a single aviation law course, it's quite confusing to try and figure out exactly what is being decided and how a ruling will affect the Feds, the States, and of course all of us.

It's really quite sad that a guy who went to some pretty respected schools doesn't have enough education to understand this very important process. Hey, at least I care enough to try and figure it out which is a heck of a lot more than most folks ever bother to do!
