1) This is an interesting concept - but also one that has failed in previous attempts (I remember seeing something like this in the past). It certainly has a "cool" factor to it - but my fear is that it's a "cool" factor only in a "perfect world", i.e., the mechanics of it will never malfunction and leave you stuck, it won't rain (or snow), and you've got good ground clearance. For a "Celebrity Mobile" or something in a movie - way cool. For me, I'm probably better off buying the Mini-van that has the sliding back door instead.
2) Was that opening shot at the Fox theater in Atlanta? Just curious - haven't been to Atlanta in a while (but should be headed back for Code Camp early next year!)
