Cops here are real funny like that. They will pull you over, hassle you about something or other, then admit they really just pulled you over to get a closer look at your bike. They did this numerous times to me when I had a TREK Y-Frame mountain bike. I've found that if you smile and act cool they usually get past the hassle part a little faster.
