that thing has a base 36.5 feet. That's around 40% of the base of my two story house... and if you take away my garage that skyrockets to well over 70% of the base.
36.5 ft in diameter*
note: that is obviously not me, that's just a person for reference purposes. I don't do uncovered knees like that, even in the snow; it's either boxers or pants in snow for me.
