>> #9 wire for your hoops.
Thanks! I'll look for that. I've been worrying about how I would bend electrical conduit (EMT?)
I seldom have snow that lasts more than a few days. I suppose we might get 1-2 inches in 2 of 3 years, but they melt soon. I could sweep the hoops as it fell, if need be.
And I've thought about one strong top rail, plus much lighter hoops and/or horizontal purlins. I was thinking of flimsy bamboo as the light componentt, but #9 steel wire might do the trick affordably.
