Several of my friends have been caught on speed cameras and it's made me edgy, even though I've only been snapped once, 18 months ago (and even then it was just over the limit on a hill near my home, where there have been very few, if any accidents).

I hate speed cameras and think, like most people, that they are just another way of attracting revenue.

Anyway, last week I was working at a school in Haverfordwest. I had to get up particularly early and couldn't find the school for ages (maps always floor me), so I was rather stressed out. I now think it was my lack of sleep and the stretching of nerves that made me so camera cautious. But on the long drive home, I saw cameras everywhere.

A light did flash on the road just out of Carmarthen, but i'm pretty sure it was for the car in front of me; but even though I was driving at an acceptable speed, I began to feel paranoid about those darn trapping cameras.

Then, near home, in the dark, I was really sure I'd been caught on camera.. a white halogen light flashed at me outside Morriston... or I thought it did. As I drove home, I couldn't make up my mind whether the white light was a camera or a floodlight. So when I got home, yawning, I drove back to look for the white light... it wasn't a camera just a floodlight keeping an eye on a car showroom, and not in the least aware of me...

Funny how lack of sleep can bring out the worst in you, isn't it?
