As an addendum to my OP, It turns out the same 'lads' were firing large ball bearings from a catapult too. Smashed numerous car and house windows around the area, also fired at a passing tractor smashing the windscreen and injuring the driver. Unbelievable. The cyclists got off lucky...
Several people caught the plates on CCTV, but wouldn't you know, not recognised. Hooky plates put on ahead of an afternoon of destruction. This sort of thing just fuels my misanthropy.
Meanwhile, yesterday was just the same as Saturday. I was on the road this time, but when i went up and over the Ridgeway, the carparks were rammed and there were groups of walkers as far as the eye could see in either direction.
I went out at 6am this morning, not a soul to be seen. Glorious. I have a feeling we'll be in FULL lockdown by the weekend, no-one allowed out for recreation at all.
