a) ultralights are not experimental aircraft
b) a 'congested area' is one with congested air traffic, not with
development on the ground. The purpose of this is to keep aircraft
which are very slow, as ultralights generally are, out of areas with
lots of civil and commercial aircraft travelling several times their
velocities, kinda like keeping the model T's off the freeway.
