I haven't seen much on this topic. I did see it on the Edge DVD's and was wondering if anyone on here is doing it. I joined my local REI and they had a speaker come in to talk about them. So if anyone out there is doing this, could you share with us how it is working for you?

I live in Wisconsin and do know someone here that does that. Not sure how that works in other states,send me a PM and I can get you in touch with him. Maybe there will be someone from DG that knows someone in your area.
But this guy is from our REI club.
