I just thought of 2 more....heights like going over a bridge over a canyon. There is one right outside of Taos, NM. Lots of people stop and get out and walk across it. Not me. Or like the brige over Royal Gorge.
And I am very claustrophobic. I went down one of those tunnels at a water park once. I thought I was gonna die...literally...before I came out the other end. I could not breathe.
