Last summer on the road I live on I was on my bike and just came out of a curve. Something caught my eye. I swerved around it and went back to look at it. It was about 2 foot wide, but deep. There is a dry creek bed under it. Hole was about 5 foot deep. They came right out and filled it. That would have been a heck of a stop... well, at least for the bike. I would have kept going...
