I've banked at credit unions my whole life. My first foray into a real bank was in Phoenix. After the looks I got depositing my meager savings, and the looks I got having to go there daily to withdraw said savings, I figured out how to get into a credit union and never looked back. Seems that place expected suitcases full of cash to be left there for years and years, judging by the marble floors and 16' wide hickory desks.
Rules are different out there for credit unions - only reason I got in was because I was a student. In MA, the requirement is that your breathing.
In light of the current political climate I keep as little money in a bank as possible, just to pay the bills. Cashed out my 401k as well. I don't trust any of them.
