Side Issues

This is an "edge break". It is about as deep as a beer can is high.
A car or trailer wheel dropping in here would make things interesting for the driver. The fact that this is on a slight curve means that this would be quite likely.
We often get puzzled looks as to what we are doing at the side of the road, rather than digging a bloody great hole in the middle.
We fill the offending area in.
OK?
