I went for my first night ride last night, it was a lot of fun and promises me a way to keep riding (at least a little) in the winter. I was reasonably well prepared for the dark and cold (needs some adjusting, but worked well enough). The only really unexpected thing was the dogs.
The short route I took last night is one I have done many times during the daylight and the couple of dogs on it know me well and we coexist peacefully. Well that seems to only be true during the daylight, both those dogs were far more aggressive last night. The first seemed to recognize my whistle and never come too close, but I did not see the second one in time to get the whistle out to warn it. Poor thing could not figure out what I was and while trying to go for the light got in my way. Fortunately, I was not going too fast so I did not go down and I don't think I did any more than scare the dog, but the surprised yelp and the running back home tells me it was not too happy about the incident.
