Me too. I opened a Navy Federal account over 20 years ago. I’ve never even thought about opening a bank account.
I opened a Navy Federal account at Subic Bay on my first deployment in 1985, back when if you were on the West Coast the only way you could open an account was when you were overseas. All the old salts had NFCU accounts and highly recommended it.
I keep some money in a local bank checking account for convenience, but the majority of my cash is still at Navy Federal even though the closest branch office is 1500 miles away. I can do everything I need to online.
