I think most of the signs are not 100% correct. It is quite a cool feeling crossing these earth lines. Sometimes we would use the GPS to take a photo at the mark they made. The Tropic of Capricorn in Salta. We also crossed it in Chile. On the coastal road in Ecuador, there's no indication you are crossing the equator. Obviously, we and 3 other overlanders had the same idea to mark the spot as per GPS. The closest thing to that spot was the road signs. That is where the stickers got slapped.
