Yep. I got pulled over in December by a cop who warned me that I shouldn't ride my bike in winter. I built my own bike specifically for the winter last year and never had a problem with it. Painted it flourescent orange and I wear a red bomber jacket with snowpants covered in reflective tape so you'd have to be totally blind not to see me riding on the street!

Anyway, he had a HUGE attitude and told me I should put it away for the winter, even though it's a design I got from Atomic Zombie's bicycle Builder's Bonanza book and it works great. I asked him to quote the laws that I was breaking and he walked back to his gas guzling car in a huff. Sometimes you have to pick and choose your battles, but as far as I'm concerned he was being an idiot for the sake of being an idiot. Ignorance is bliss. Some people have nothing better to do except complain and harrass those of us who are minding out own business.

Everyone who rides a bike seems to be painted with the same brush, so I wouldn't sweat how you were treated by the cop.
