Hehehe - all the discussion so far greatly fascinates me and has all sorts of gears turning in my head. This is great - new viewpoints, new thoughts, new problems, new solutions - I'm learning stuff.<br><br>Chris, Doug - do we need to cart this thread off to the Campfire Forum, or is it OK to leave it here? I vote for leaving it here, but I'll support your decision either way.<br><br>I disqualify myself from making informed contributions - I live close enough to my office that most of this discussion is academic to me, and I jumped horses a year ago to something that makes business travel strictly on my terms (rare). BUT - I have family members who share many of the environmental concerns being voiced here, and I hope to learn enough to pass on to them.<br><br>Do any of us who work (or perhaps also live in) "big" urban areas keep a big walking stick at work? Or perhaps commute with a smaller "walking aid"?<br><br>Tom
