Ulli dedicated this sketch to his Mom, Gerda,
who celebrated her 83rd brithday on February 3, 2011,
and to his Dad, Hans, who would have celebrated his 86th the next day.

Ed Mitchell walks away from the Apollo 14
ALSEP Central Station, letting the two lines
for the Thumper-Geophone experiment unwind
from the spools on either end of the bar he's holding.
