Is it something about tandem riders(I also ride a tandem part time- simple Burley Duet-nothing fancy(nor is my wedding ring), but it is fun)...I am usually a minimalist, makeup wise, but for some reason adopted a habit of lipstick for rides...bright red for big rides is my good-luck charm. I tried nailpolish once, but it was too obvious and bugged me the whole ride. Lipstick on the water bottle...yeah, but it's MY water bottle.(and here's the practical side of it...protection from sun.)
