I was slightly incorrect about the amount of traffic. The street doesn't get much traffic on our end, but the end I started on had quite a bit more include ATVs and other loud vehicles. Stinker was a little nervous, but he was quite steady. The traffic thinned the closer I got to our end of the street.
Once I turned onto our street I pulled out my phone to check messages, because there is only one other house on the street and I wasn't expecting any traffic. Plus he was eager to be home so I didn't need to worry about steering. Except he hit the brakes, spun, and gave a half hearted attempt to bolt.
Thankfully, I have a well installed verbal cue for easy bud so he didn't actually go anywhere. I was really confused what freaked him out so much until I got him turned back around. Our neighbor was riding her bike and wearing Christmas light (so she could see and people could see her). Poor Stinker thought it was the most terrifying thing ever.
I felt bad, because she kept apologizing. It really wasn't a big deal, because I should have been paying attention. And it wasn't her fault that my horse spooked. I don't blame him for spooking, because I am sure it looked terrifying to him instead of amusing. But now I know to watch out for cyclists wearing Christmas lights in July.
