And most of them bad.
It's a bit notorious. I certainly wouldn't fancy doing a night there, or leaving my car on the car park when it's not daylight!
Not trying to put you off, but someone was shot dead just over the road and a bit further down on the car park there, a couple of years ago. Think the police described it as "drug-related".
As far as the fishing is concerned, I used to coarse fish there a long time ago, and I saw some large 'shapes' in the water by the reeds on the right hand side of the 'island'. In the channel. I spoke to three guys who had done a night on there in the winter of 2006/2007 and they'd been told by the Park Ranger that there were carp to mid twenties in there. It was bitter cold, and they hadn't had a run all night, and they were waiting to be picked up.
Make of this what you will, but they were moving their gear to the car park in turns. One in the car park, one at the pool, and one carrying the gear from the pool to the car park!
