Beside a few exceptions like doughnut holes and breathing holes, they are typically bad news.
But the worst hole of all, since most of us will never actually see a black hole, is the pothole.
And according to this week's Red Phone e-mailer, there is an especially nasty one on San Felipe Road and North Street.
Our hero, the Crimson Crusader, fears no hole. But for those without catlike automotive reflexes, their best bet is stopping the problem at the source - filling in the hole.
The Crusader talked with Hollister Street Maintenance Manager Ray Rojas who said potholes must be at least three inches deep to get fixed.
"If there is a severe pothole we try to address it right away," Rojas said. "We usually send a crew out once a week on Fridays to fill in potholes. We've also had a lot of cutbacks on funding and unless the hole is three inches or more deep than it's not a priority."
