The Council has kindly provided a map of the free fishing in Harpenden on the Upper Lea. Here’s the map and some thoughts on how to fish a couple of sections. Nb - if you are 13+ you still need a rod licence.

I think most parents worry about screen time and many would accuse me of being an idiot for asking a child I was teaching if they preferred fishing or minecraft. It turns out fishing (or more specifically catching) is way more fun.
