I have friends that still ride and I honk and wave as I go by, but it is the "experienced" riders with the numbered jerseys that ride 4 abreast that are the problem. I am sorry if that offends you. Wait, no I am not. What they are doing is both inconsiderate and illegal yet they go all high and mighty when you call them on it.
Jeff, make sure you put some "bait" in the middle of the road. It is easier when they are stopped.
It almost works for Wile E.
