Today in the Süddeutsche Zeitung, you can read an German article about our dude Lukas, talking about the Isar river and the work of Munich's fishing club "Die Isarfischer e. V." regarding restoration and fishery management.
"I've seen a big one right above that third weir down the bridge. You better walk on the gravel bank from the right side, otherwise you could spook them. But it really doesn't matter because there are many huchos in that area."
My first years of fishing I spend on little ponds with a normal fishing rod, catching stocked trouts and carps. Some years later I read one of the "flyfishing for beginners" articles in a normal fishing magazine. I was directly interested in this "unknown" fishing technique and started watching videos about it.
