I myself dont care sure some times I enjoy the privacy but if I really want solitude from people when fishing, I am not doing in local rivers like chehalis, vedder, harrison and fraser, thats like complaining about how vancouver is too busy.
What's our population like exactly right now in Vancouver BC? 2.1 or 2.2 million people? Gonna run in to the odd person that likes to fish I am sure. It's something you just have to get used too.
One way or another people are either going to hear about a place like Chehalis or find out from pro shop or online, seeing as there is more then one website to get that kinda info from and not all are gonna hold that information in the same black helicopter secrecy.
