I love getting into the conversations late. Like others I have made it through a few decent thunder storms. I big tarp is well worth it. Plus it gives you a try place to setup and tear down.
Unrelated, I did learn that it scares the crap out of me when the trees are swinging in the high winds. The distance keeps changing between the trees, really fast, and I get a bumpy sleep. Kind of unsettaling the first time. Fun after that.
