Today, two strangers waved in response to my hand signals. They were not gestures of greeting, I was trying to make a turn at a stop sign. That's the third time this week. I hope our friendly culture doesn't get me into a traffic accident! I wonder if there's some more exotic way of signaling left and right. It's been a very long time since I learned bike hand signals at Safety Town, but I think if I bend my arm at the elbow and them straighten it out that might clarify things for drivers. We'll see.
