Is there anything about the wind sock that can let one know the mph of the wind? Just curious
Still and flaccid: 0-2 mph, possible low temps.
Free-swinging/flopping around: 3-8 mph
Partially erect: 9-14 mph
Completely straight, full throbbing erection: 15 mph+
The picture posted above appears to have been taken at the 3-8 mph range.
