Just as a point of interest these two pipeline patrol pilots do often
meet up in the air. A long while back they decided that one would fly at
400' AGL and the other would do 500'.

You have to get a waiver to fly a 500 foot altitude at all times. They
don't give waivers for less than that so the 400 foot guy was busting
the reg for traffic purposes.
