I like the points about keeping things on your person. I think I will adopt those practices. I also like the point about theft. I think I will just keep the copy of the health insurance card and cash on the bike. Thief cannot do much with insurance card. Willing to risk a bit of cash.
I like the idea of these things living on the bike as backup. I sometimes forget to bring things. Or I head out for a short ride and change my mind and decide to go on a long ride. Nice to know I always have lunch money.
