It's winter. My pack will be heavier. I will also be carrying more water on Saturday.
XTrekker, do you and your wife each have two sets of dry clothing? Also, will her parka and any other layers she doesn't wear while hiking in fit in her pack and stay dry?
The FS says the rains have made the roads wetter than usual, so I'd guess the stream crossings will be, too. Bringing Crocs and 4 pairs of socks.
