Some additional rambling thoughts here. 

I normally carry a couple of military foil packed trioxane bars, some waterproof matches and a waterproof/windproof  butane lighter that you can actually light tinder with, most will not. This just goes in my PFD pocket because it is all waterproof.
I agree with ST that solo travel comes with additional concern and to that end I like Magic’s idea of attaching it to the PFD as well.  Trying to remember where my emergency gear is during an emergency does not seem like a good plan.  Based on the suggestions of others here, I will be adding to what I carry, in or on, my PFD.

My only other comment is about medications.  During my yearly physical I ask my doctor for a script of broad spectrum antibiotics for infections from cuts or other internal bacterial issues and also a script for some high powered pain meds.  Our group has never taken a single tablet except at home prior to the very first trip to make sure there will be no allergic reactions in the woods.  The next year I give them back to the doctor for disposal as proof they are not being used inappropriately.  After a year the antibiotics are losing potency anyway.  Neosporin and Band-Aids works well for blisters, but if someone in the group has a broken bone or a raging bacterial sinus infection, some meds would help manage an un-happy camper.

I fully expect some dissenting opinions, which is great because the forums have been too quiet lately anyway.

Kind Regards,
