What domesticated ape said upthread was what worried me, getting it all into the panniers, especially since I've only got the fittings for one pannier on the bike! I've loaded most of my gubbings into the Yak Bob Sac, and it fits, and is pickupable. The extra sleeping bag and mat for NSTN may have to sit on top in another bag.
I haven't tried towing it, but it shouldn't prove a particular obstacle, since I've certainly towed more in the past, only not over such a distance.
Like Wow I've got everything upto and almost including the kitchen sink, I'm not sure whether to bung a couple of bottles of beer in there as well, or if I'll regret that when I hit a hill!
Final packing in the morning, including squishing the sleeping bags into their stuff sacs, and odd and sods which I need to leave out until the morning (like my toothbrush!). Now it's time for bed!
