How easy is it to cross state borders in America?

If you cross the border between England and Wales or England and Scotland there's normally a road sign telling you. On major roads these can be quiet large but on smaller ones they're often very small and easily missed. There's no checkpoints. Roads can weave in and out of the border and place names and signage both sides is often in both languages. It's not unusual to not know what country your in.

And this has got me thinking, is it the same in America with state borders? How easy are they to cross? Are they well sign posted or is it a small sign on a lamppost behind a bush?
