Pollard, thank you for the suggestion! I wish I had room for a high tunnel! (Like the one at the photo link to your home page / Pollards prepper links!)
One of the reasons I am using a lite weight insect barrier is cabbage loopers that totally destroy any cabbage type plants.
I'll use it as far into the season as I can.

Since mine is small low tunnel I have been throwing something on top to keep it from blowing away and that has worked so far.

However, I have some of these squirreled away somewhere and I think I'll dig them out:

Coghlan's Twist Anchor Plastic Tent Stake, Orange $1.88

These are meant for tents for camping and I would NOT use these for a real high tunnel, I would use the ones you mentioned.
(I used mine as anchors for the paracord for my suspended tomato plants!)

**Looking at that high tunnel, it might make a great run for poultry. Till the soil, put the coop at one end,
put up your high tunnel, provide ventilation, and let your chickens eat and fertilize the run, and occasionally move it to your next vegetable plot. (Says the man who has no poultry!)

@Pete. Low tunnel, high tunnel, is just a matter of size, materials used and features. Same concepts and basic purpose. I just grabbed the only pic I could find that showed the cross roping. People use them on all size hoop houses, low or high. Those tie downs would probably work good for your hoops along with some paracord.

@Diana in Wisconsin - @metmom. I’m in hill country and you never know what the winds will be like here. Straight line on occasion with a lot of gusts from variable directions depending on how it funnels through the hills. We’ve had 60 mph winds but it’s been a few years. There are a couple of spots within a mile where no one should ever build. Something about the land shape pummels those spots and breaks off or uproots healthy 12+ inch trees.
