Yep, the SWT is a big "sail" and it was a windy day. Not cold, temps in the 70's-80's. Steady wind over 15 MPH with gusts up to 30 or so. Honestly, it was a bit much to ask of one of those little plastic Figure 9's.
I happened to have a bigger, metal one in my pack so I used that to get the tarp back up.
But, that's the cool thing about playing with gear when you're 20 yards from the house! If something breaks, you're not 10 miles back in the woods.
