I live in Central Texas, and it's already in the upper 90's creeping ever closer to triple digits.

As far as cold weather camping goes, I've got that covered. But what do you do when it's hot?! Assuming it's a calm night, it may not get below 80. There's no point in taking a 20 degree bag out on a night like that, and there's barely any point in even trying to cover up! So what do you sleep in/on? I've got a $5 tube tent to keep bird crap off my face, and a light sleeping pad, but what else? Do you even bother?
Oh yeah, first post. Hi.
