Yeah, it just kind of....happened.
One guy that either was or is part of one of the very active bassin groups was outted, and fined. Back when it was more or less one big group of BC Bassers. Now there are several groups/allegiances/divisions whatever you want to call them. And I think he was 'outcast' from all of the clubs, at least on public forums.
But IMHO, others either knew, prompted others to do it, or otherwise turned a blind eye. Then when the one guy was outted, everyone in the community could point to him as the sole cause of the spread and wash their hands of it.
Anyhoo, if there are bass in some waters by some means or another, they are there now, I will fish'm. Especially in places that don't really support our 'native' species.
