Last week I noted to a friend while we walked home that I thought a dip in our road was getting worse. True enough, the next day on our way to work there was a big hole where the dip once was. Coming home we saw the hole had been "repaired", ie. filled in with rubble.
Shockingly, this method didn't seem to work as this morning the hole was back, this time with a branch poking out to alert drivers.
