When u ride with a group of trikers r there any special tips on group riding, for example for road debri, formation, lane change, hand signals (for handi cap). I know most of the rules of group riding are prob. the same for 2 or 3 wheel riders, but I would worry about road debri approaching, because of not being able to see the road ahead of some of the trikes, unlike the way u can see from behind a 2 wheel bike.
