well according to what it seemed like when I was out there it was much colder than 21 .
but then again with a north wind of 15 to 20 I guess it might have been a pretty decent windchill factor .
I will tell yawl a fish story about it later when I feel more inclined but to be sure I about froze to popsicle grade in a very few minutes .
sometimes the jungle is not a warm place to play I tell ya :Rofl
