I am going to look into that book, thank you.

I believe bikes might trigger the camera since a motorcycle has before. I just usually stop in the shoulder so cars will pull up to the line. I will probably talk to the Sheriff I see around town and ask him in this case what I should do. Honestly I think they would not even attempt to ticket but I hate the way it looks to anyone nearby! I really think (hope) it was a random act of horrible violence.
