Only for a fairly restrictive definition of “big”. Kansas City, St Louis, Twin Cities...easy to say hi or start up a conversation. Unfriendliness only an issue in dense cities with a high quasi-transient population or maybe a boom town. Even there, if you look for the persistent villages beneath the city...which is the classic NYC response. Intermountain West, Deep South sans south Florida, Appalachia, Desert Southwest (maybe not Las Vegas or Phoenix or the boutique tourist towns in high season, hard to say), New England sans Boston...not really a problem.
