I know it's a long list - and I don't take all of it everywhere, eg, if I ride in my local woods I don't take as much stuff, but if I mission off to do the SDW then I take more.
Thing is, I live alone and do a lot of riding alone so not only do I need to be able to cope with an emergency but I also need to FEEL that I could cope with an emergency. It's a confidence thing. I don't have anyone who I could ring for help so if the doo-doo hits the fan there's only me to deal with it. I find I can manage most situations with a fresh coat of lippy
I don't take the toilet paper on a roll BTW, and I need it cos I'm a woman and we do wees differently to guys (but you knew that already) and blowing snot-rockets is all very well but it's really nice to actually blow your nose on some toilet roll.
I have found over the years when I do ride with people they start out laughing at my kit, but as sure as eggs is eggs before the day is out someone will sidle up to me sheepishly and ask to borrow/use something.
