To answer your earlier question - yes, I used to fish the south Wales coast in my early teens.
It was largely a frustrating experience of getting snagged a lot, losing tackle because no one showed me how to tie a knot properly.
I had no idea about tides, correct setups, bait etc. It was no wonder I seldom caught anything.
Nevertheless, for an urban kid like me it was just great to be next to a beach.
