Hey Greg,

I was going to suggest putting the guitar on your left leg. It's because the angle of your arm and position of the guitar neck isn't optimum when it rests on your right leg. Your own body will get in the way of fretting, and a lot of guitarists will start squirming around and leaning, pointing the guitar neck out to try to accomodate. Moving your entire guitar to the left of your body solves this and gives you way more access to the higher frets.

Classical guitarists have it figured out. :)

Here's a video in which Steve Vai talks about the injuries he's had, some of it from putting the guitar on his right leg, hunching over, and raising his right shoulder too high.
