There's a stretch of road for about three blocks on my route, where there's a bike lane but no sidewalk. This is in a newly developed area, so I get a little irked at the planners who apparently didn't even think that the area would be traveled by pedestrians. People walk in the bike lane all the time. I just move over to the left, into the non-bike-lane, and give the peds plenty of berth. As someone who was all-ped-all-the-time a few months ago, I know bikes can seem like they're buzzing you when they're really not. 3 feet minimum is the closest I'll get to a ped.
