Bob,
I really enjoy going through your pictures, thanks for taking time to do all those captions - I know it takes a while. It's interesting to look at the way other people handle water/gear/etc, especially someone with so many miles under his feet. I'd be interested to see if I could make do with a 19 pound pack, my cold weather climbs have me carrying just shy of 50 lbs. Lot's of shaving to do.
This bivy you've got, it looks like it could be one made by that gent from SAR that has created a few designs - I think Doug has one in the shop. Is that correct?
