I added that after my first visit to the Cape - I had never seen a sign like that before (or since). I thought it was funny. I think I understood its meaning but felt like it could have other interpretations too.

The other thing that was different about driving there were the huge rotaries. I've seen roundabouts and traffic circles before but haven't driven around anything that large anywhere else. I actually had to count the exits out loud to keep from getting confused and just going around and around the circle.

I have never heard of a frost heave or a reverse curve. What are they?
