I second the idea to carry a COPY of your driver's license and insurance card. I keep mine in a small zip-loc baggie along with some money ($10-20) and what ever loose change accumulates. I have one on each of my bikes. Never have to worry about transferring back to my wallet after a ride. Hmmm - with 3 bikes I guess I have ~$50 stashed away. This way if I end up stopping somewhere to get coffee, snack, Sunday newspapers, whatever I always have enough to do it. When I get down to about $5 to $8. I replenish my supply.
