Once in a while you discover a website that makes you smile – yet is hugely helpful. If you are a cyclist or motorist, take a look at Fill that Hole, a new website from CTC, Britain’s national cycling organisation. It’s an easy and fun way to report road defects such as potholes to highway authorities.

If you’ve encountered a pothole, you simply locate it on the (Google) map. A very satisfying flagpole appears. CTC will then report the defect for you.

The Guardian reported on this super idea last week in Matt Seaton’s cycling column. As Matt said, Fill that Hole is so good that we’ll soon be looking for potholes to flag. A sister site, Clear that Trail, covers offroad trails.
