I can group most comments to me in three general categories:
1. Wow (or the expletive enhanced verbiage), that was a bike!
This one comes from other cyclists and pedestrians that are amazed to see a bike with a good lighting setup.

2 Harrrrrrrra blarrarrrr!
I hear this, or some variant from most of the vehicle occupants that take the time to comment.

3. The drivers of cars that are considerate enough to slow down to tell me what they think generally question my sexuality or intelligence, thereby announcing their own.

The most recent comment I received was from an inebriated soul recently returned from the purveyor of potent potables. He was in his driveway at 1:00 am. He was kind enough to inform me that the speed limit of the road I was on was 45mph. To which I responded: "I think I'm safe from a speeding ticket tonight."
