Lol I measured 16 as well and I know EXACTLY how you feel.
During NEMO I lived in Norwalk and was disappointed i missed the 30 to 40 inches east of me (ironically where I live now). I measured a pedestrian 22 inches.
Now I had 16 and even Bridgeport reported 20.
Only 1996 (27) and 2006 (20.5) was I on par with the top measurements.
