I deal with a few phobias and am trying to picture the drive down I-75 from Atlanta to Orlando. I am fine on short bridges and underpasses---the long ones, however give me some problems. BRIDGES: Shot ones that go over rivers are okay. Long ones over lakes will give me trouble. Really high bridges give me trouble, too. TUNNELS: Underpases are fine, but long tunnels, especially when I can't see the end are pretty tough. Does anyone know what I will be facing on the way down? I'll be taking I-75 all the way down. Thanks!
