This is somewhat what I'm using for a run right now. I don't want to take it down for the winter. Can y'all think of ways I can keep it standing thru the Upstate NY winter? I plan to use plastic sheeting around it, leaving a 12" or so gap around the top for ventilation. But I'm worried the whole thing will blow down.

along with actually measured size of tubing, and how tubing sections are connected.
and yes, it earned me some good bucks over a 20 year career.
