I was driving into town the other day and came up to this. It look me awhile to process what I was seeing. A traffic light?
I eventually discovered that they were working on the road just around the corner, where I possibly couldn't see.
I thought it was a bit unnecessary considering the amount of traffic on this particular farm road. Plus we don't even have a traffic light on the highway in town.
The light cycle took 5 minutes. It usually only takes me 5 minutes to get all the way into town!
