There are a number of heavy pedestrian ways that are hard on tri-pods
on principal around the world. You can catch grief in Manhattan! If
you were lucky enough to visit Rome in January or February you can't
imagine the crowds on the Via dei Fori Imperiali or St Peter's on a
Saturday or Sunday in August or on a Tuesday in May for that matter.
You might think about a monopod for those kinds of situations, pass it
off as a walking aide.
