METARS showed some reporting stations in the 1900
overcast range, but most were at 2200 or better, and radar was clear


As we approached Dubuque's Class Delta airspace, the ceilings dropped to
their expected low-point of the trip (the Mississippi River valley usually
creates its own little weather pattern.

I had to remain at 1900
feet to be legal.

How did you stay legal (500' below clouds) at 1900" if ceilings were 220' and
sometimes lower?
