Bootin the skin track is BS.
A few years ago I was at Targhee and they opened up Molly's Nipple for the first time in a while. There were like 40 snowboarders in front of me booting. Being the ever prepared skier I put on my half skins and chilled near the back until the first guy was several hundred yards from the top. I then made my pass, every boarder was yelling obscenities at me. When I passed the lead guy he yelled at my for skinning in his boot pack. He threatened to kick my ass. I told him to meet me up top and he could try, as he caught up to me, he literally threw off his gloves an came at me. I just clicked in and put in about 4 giant turns off the peak, over the cliff and laughed the whole way.
In the san juans bootin in the skin track isn't usually a problem unless you ski where all the other jack asses ski. A competant skinner/skier can be miles away from where even the most determined bootpacker can get in a matter of minutes.
If your favorite area you frequent reagularly is getting booted, throw in some 'dummy' and stupid skin tracks, for bait. I have tried that and it is funny to see some booting a dead end skin track i just skied out of.
I have found that if you have problems with bootpackers you arent far enough off the beated trail. Usually putting a skin track through some heinous treed switchbacks will discourage most booters. Exceptions are Teton Pass and other places where boot packers are a plague.
Here to a kick ass winter shaping up, even for you boarders...
