I am with most everyone else, if it nice outside, and I am not worried about the wind, then I just leave it off. If it is about to storm, then it goes down low, and sometimes the ends are closed (on my Cathedral Cat Tarp). I also like to put the wind side down, but put up the other side like a porch using my hiking poles. To each their own, whatever best serves you.
Psalm 19:1-3 "The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard."
