Walking seems to give me more diversity in sight-seeing options than cycling, that's one thing. If bicycling through a neighborhood, so often I'm concentrating on the traffic, the road conditions, etc. etc. and it's difficult to take in the scenery. Of course, being on the bike is better than being in the car in that respect. But with walking, you get to see everything - the gardens, the buildings, -- ya get a real feel for the neighborhood. I really enjoy that.
