BTW I got the post for my mailbox the next day. Decided to cement it in and bought a bag of concrete at HD and was telling clerk.

Skip the concrete and just bury the post about 3'. Nice thing is that if you have to replace the post, you can usually pull the old one with a floor jack and slip the new one in place. No digging required.
