I think that's right. Large swathes of coarse fishing have developed in ways comparable to carp fishing.
Peter speaks of inventing and testing rigs and baits as part of the interest and challenge. That was a different world to my fishing, but it was common that we made floats ahead of what could be bought, made feeders, bought blanks and made up rods, spliced in quivers, made swingtips, bread punches, catapults, plummets. Anglers with fabrication skills or mates in such jobs had platforms, rod rests and bait trays they designed themselves. When poles came in, we made bushes, bungs, feeding cups and tiny floats. My first two or three seatboxes were made in the garage with help from my dad. There's a world of initiative and inventiveness there that's very different to coming out of AD with your arms full.
If finding carp was a different matter back in the day, finding some decent general fishing, or even some fishing in some areas, was a different game. By bike, then motorbike and then car I'd scour the area for miles around, just nosing around, or with OS maps or on pointers from other anglers, with ponds, pits, canals, estate lakes, mill dams, streams and river stretches all on the agenda. We'd have a stock of "big day out" waters that were maybe 50 or 60 miles away but worth the trip, getting you to beautiful places like the Upper Severn or Middle Wye or some sleepy estate lake in south Shropshire. A world of exploring, seeking and finding and changes of scene. I know anglers in their twenties who are happy to get all their fishing at one of a couple of local complexes where concepts of beauty and exploration are irrelevant.
It's not only in carp fishing that getting yourself equipped and tracking down some fish have changed. Short cuts are available in abundance. I'm glad I got here by the scenic route.
