Some riders like to bring some trinkets to give away to the people who are giving out water and food, the kids hanging out at controls, or other riders. I have a nice pin a rider from Seattle gave me that shows an outline of France with the course drawn in red. I brought a handful of pins, some RUSA ones and some USA/French flag ones, and gave some away in 2015, forget to bring the leftovers in 2019 in the flurry of last minute packing. If you're going to PBP this year and want some pins message me, first one or two folks who ask get them.
