I certainly wouldn’t call that “well-traveled” and bragging is kinda dumb in general, but it is worth pointing out that the US does have a huge diversity of different cultures, demographics, and environs in different states (so much so that they can often feel like different countries), so it’s perhaps not as quaint as it sounds. It’s not like traveling within a European country. Much closer to traveling within the EU.

Still would never call that being “well-traveled”, though.
