Hoover Dam and its new bridge give me the heebie-jeebies. They're high. Soenke said he felt like a beaver during the visit to the dam (you work with that for a while). On the way east, we stopped at a humungous Walmart to pick up supplies. Our least glorious moment came when we could not figure out how to lock the rental car. It has an "intelligent" key or some such thing and the three of us could not figure out how to get all the doors and the back locked. Come to find out, after driving and thinking and testing out... when you hold the key and pull up on the locked door, it unlocks because the key is within one meter of the door. If you could have seen us in the Walmart parking lot... well, you wouldn't have been impressed. Now, we're just outside Flagstaff AZ and tomorrow we head to the Grand Canyon to climb down Bright Angel Trail. Then, we'll drive to Sedona. Off to eat at a BBQ place in Williams AZ. More later!
