Just providing info. I wasn't trying to say that the Mythbusters did
anything conclusive. They used reasonably solid bridges and small
robot "soldiers" for their test. I would say, though, that they made a
good case that any average bridge in place at that time (not a
swinging foot bridge) would be hard pressed to go into normal mode
vibration as a result of marching soldiers.
