Stoker can reach stuff in her jersey pockets and even the trunkrack bag. Of course captain's jersey pockets are easily accessible. A bento box (attaches with velcro) on stoker'stoptube also works for holding small stuff.
Cue sheets attach to capt's rear jersey pockets with roach clips/clothespins (remember those?) or safety pins. There are also several cue sheet holder available for either rider.
Be innovative!
