The idea makes me light-headed...I have a serious phobia when it comes to bridges. I cross 'em. I don't try to avoid 'em. But I don't like 'em and I have life preservers for my jedis under their seats in my van. I don't care what anybody says...I feel better with those life preservers there.
I'm not real fond of highway ramps that come up off the ground either.
I don't like bridges either ... or long spanned freeway overpasses (we have a lot of those here in L.A.). I also hold my breath going through tunnels ... and waiting at stoplights under freeway overpasses.
