LOL about 100 miles in a week? that's like 160km. That' fast as hell.
I've been on WCT, Golden Ears, Manning park. Tried to do a night without a tent and only a tarp. It sucked, both times I tried it.
Was supposed to do NCT with a group of friends this year but I landed a new job and it'd be bad to ask for a week off before the 1st day.
I'm in the market for a down sleeping bag right now. nights are cold as shit.
My pack is a 48L Osprey Kestrel. I'm pretty happy with it, it's got lots of room if I strap my 2 person walmart tent to the lid, and bring 2 pairs of clothes.
