That is always a good place to slow down. Always. I have seen them standing on the side of the road just pointing at them and pulling them over as they come around a corner. I have wondered what would happen if a car just kept driving on by them. Waving as they passed.
This is the third time I have heard them doing this in the last month but I have never heard them doing it on back to back days. That doesn't mean tomorrow they are not doing it just that they have not done it before.
