Wow! The idiot who painted that on the road is truly clueless. I've ridden around Grass Valley and thankfully never encountered the idiots of the road. As for the person making comments on your YouTube video - I have to say the comment was certainly one of the more respectful disagreements I've read. The comments in SFGate are downright ignorant while the person on YouTube simply stated how they thought it was unsafe. It is a far cry from the people who comment about how cyclists deserve to die because we are on the road. I liked how they didn't say anything personal but kept it to the idea that the road was unsafe. The part about staying on bike paths was stupid but at least not mean. If all anti-cyclists kept that tone the discourse might not be so vitriol.
