Again, Thank you all for you feedback on the trip report. I'm so happy you enjoyed it. I hoped it would be as inspirational for you as the trip was for me.
Omar, yes-my pack is the ZPack Blast 3200. I absolutely love the pack. It is extremely comfortable with all load sizes and is extremely hardy and waterproof. And at 6 oz (with options on) can't beat the wt :) I can compress it for smaller loads and it has plenty of room for my gear, including the bear vault. I have not had to use the collar extension
