Google Earth has come a long way...this rendition looks almost as good as an aerial photograph. You can see exactly where I was standing when I took my series of hypers. The first bridge (dark color) is the Big Four. I was standing on it over the curved ramp leading up to the bridge deck (ramp looks like a bass clef symbol on a music staff). The buildings of downtown Louisville are in the background.
