Best places/areas to collect old tvs?

[StarquestMan]

Ive noticed where i live in siskiyou county CA that pre 1980 tvs are now pretty much non-existent now. I've heard on one post that some places are hard to find old tvs due to certain factors such as storms that occasionally destroy everything or economic factors like rich areas being quick to get rid of old technology or poor areas that couldn't afford it to begin with. This made me wonder what areas or even specific types of places where the odds of finding an old set may be higher?
