I've thought about and plan on carrying a Mt Bike or some sort of folding bike in my truck for just this purpose, add a rack on the back and a couple bags for your gear and your set to go. I work different places owning a cleaning business so walking would be hard if I had to go back and forth, especially carrying supplies, so either a two wheeled bike or even a three wheeled one would best suite me. But I agree, trying it before you actually have to do it in any type of emergency is the wise course. Another thought is the less obvious you are (camo yourself according to the surroundings) the better your going to be. Situation's would dictate weather or not you would attempt to walk home or wait out a given emergency, so having supplies at work, in you car/truck or your route home might also help. Sounds like he's on the right trac so to speak, something we all need to consider.
