Our worst winds are westerlies and I always orient the tunnels east-west. No chance with with whirlwinds though!

Whirlwinds Steev? Where do you get whirlwinds there? I never noticed that phenomena.
Is there a brand name associated with the fabric Raymondo? I want to see if I can come up with it. And the hoops are just bent pvc pipes?

It's called Insulnet. Not sure where it's made, China no doubt. If you have no luck Googling that then try suppliers to the horticultural industry. I got mine from one such supplier. The pipes are just poly pipe (?pvc). Any rural supplies store should carry it or something similar. I used 3/4" but the next time I make some I'll buy maybe 1 1/2" because the 3/4" is just a little too flexible. You'll need something in the ground on which to push the pipe ends. I used some old metal rod I found.

We use electrical conduit. Leo found some small diameter re-bar and cut them. I pound them in the ground and slide the Electrical Conduit on them. Johnny's sells a conduit bender, that's really easy to use.

That looks like it wouldn't tear but still let air and light through. I hate to use a thicker row cover on brassicas and sweat them out but -ah who am I kidding? My winds are so bad nothing high profile stands a chance.

Jo, I'm not talking whirlwinds in Oakland, but on the farm; they come through all the time, just dust-devils, but very robust; I can hear them coming 100 yards away.

One day this spring when I laid plastic on the paths and row cover. About 4 o clock came around and a little dustdevil came and went over the area I had just laid the stuff in and then moved on. It was so ironic! It showed me any 'weak' areas.
