They range from the odd and the amusing to the bordering-on-illegal.
My movie moment came on Sunday.

The first day of summer brought out an urge to be healthy, so I cycled from Long Melford to Sudbury along the disused railway track to return the previous night's DVD.

It seemed I wasn't the only one enjoying the end of another long, damp, one-weekend-of-snow winter.

Hordes of families, dog-walkers, cyclists, horse riders and hikers were out in force. It was a vision of a healthy England tipping into a happier climate.

But the seasonal honeymoon began to sour on the return leg.

I'd seen them on the way into town – a furtive-looking lot in hooded tops, looking cold despite the warm weather.

Gathering speed along the track, I was suddenly stopped in my tracks by a tree lying across my pathway, snapped near the base and dragged from the splintered wound. A few yards ahead I hit a wall of branches and young saplings snapped or wrenched over, then piled high and wide across the track.

I started clambering over, slipped, fell on top of my bike, the pedal striking a part of me I'd rather it hadn't.

Suddenly I heard sniggering, I looked up and there were the furtive hoodies, shrinking behind the bushes with one pointing a camera at me and filming my struggling to remove the bike and myself from the freshly constructed barrier.

They're a savvy lot – not long ago cheeky kids would create a little mischief and scarper keeping their escapades between them.

Now they video it, take it home, put together a short film and post it on the internet for the world to see.

Really – these kids have it all – the urge to break things and the technology to make it global.
