took a boat ride to Hoover dam about the only way you can see the bridge. when we lived in ariona we drove over the dam many many times getting to reno where family was. after 911 and the restrictions on bridges tehy moved the highway to way above the dam. we did cross over the highway as well and you can't see anything but a barrirer. next time we might take the dam tour I guess from there you can walk across the bridge and see more.
by the way thanks to Kate at little somethign for the tutorial on doing frames in photoshop. i added a link in my tip section but you can check her page out here
