As for knowing your riding PARTNERS...KNOW THEM. Find out if you should be aware of anything. It can be an allergy. I carry in my wallet all my health info, have a copy in my saddle bags, and I do go to the extreme as I also have about 1 dozen laminated ones. If I ride with someone, I hand then a card. Ya never know. No one ever complained and its more for safety for all of us. If i am a lead bike and go down, I can potentially hurt others.
