5. IF driving by something counts, ive been by the Arch in St Louis.
I will say this, if you havent been to St. Augustine I would go my family went down and walked through it years ago, its very nice. Just bring lots of water because its hot.
I've been to 18 in person unless I have to have actually been inside in order for it to count. For example I've been to the White House and the Washington Monument but I haven't stepped inside
