Locals making fun of lures this is always the case, till you catch something...then everything changes.
I remember the first time I went deep sea fishing from Bandra offshore trolling large lures, the guys were quietly chuckling, that is till we landed a nice Cobia, then they were actually scared, because the boat was not really a good one and they were worried if we landed something really big, it would damage the boat, we were over 26NM off the coast. Then we had an accident and had to turn back....
Back to the topic, I have seen locals who were given tackle, lures, Rod and reel really rape the place, because these guys had nothing to do, they were jobless, fished morning and then afternoon to Night literally and almost daily. They sold the fish they caught to make a living from it.
