Are you including the building materials into prepping?

How are all of you keeping this stuff from warping, you can't leave a 2X4 anywhere in Fl for very long and expect it to stay useable

I will add. I'm having a hard time finding good dry lumber here in Florida. What I've learned is to stay away from buying from places that you can see that they store they're bunks (large pallets) unprotected out side. I think what RP is saying falls under ether kiln dried lumber that is poorly dried or has been rehydrated by rain or high humidity when it's stacked and banded. What happens is they bring it in the store and remove the bands and for awhile it's all nice and straight until it starts to dry out again even after you have bought it and have it nicely stacked or even used it for a build. When it dries it will twist, cup or crown (bow) badly. So... Pick your lumber carefully.
