Lizards and sandy soil

[KITKAT]

I've been hearing lately all kinds of things about lizards liking sandy soil. Such as, there are few skinks in our area because our soil isn't "sandy." Georgia has lots of lizards because it has sandy soil. But I just can't figure out the correlation. x.x

Every gardener knows that if you want good drainage in your soil, you add sand. Thus, sandy soil should drain water better than soil that lacks sand.
