My main accounts are at Wells Fargo.
Opened my account there while OC, with a check from a legal settlement from a local PD who overstepped their authority because they didn't like me OC.
I used to use a local credit union & OC'd all the time, even have hidden camera video of one transaction. But when WI finally got cc they included a bit in the trespassing law allowing businesses to post "keep out, evil gun owner" signs and that credit union did it.
As soon as I can financially manage it, I will move my mortgage away from them as I have taken my everyday banking away.
