Hey, it's okay now. One end stretching the tarp tight over the main rope ripped out and the end of the tarp is vertical. So no major tarp failure, which would have equaled a flood. So I am enjoying the slow, soaking rains I am getting.
I will fab some wooden blocks that will hold the rope, while the tarp is sandwiched between the two blocks with screws. I will get these up as soon as it quits raining, so sunshine will come back ASAP.
