Anyone lay their own concrete?

Its a sandy area but im gonna try lime over the sand as a base rather than class 5 gravel since lime packs so well. And fiber rather than rebar for the shed little cheaper and easier to work with
Yeah, sand is very, very good. I have clay where my pole barn is. Horrible stuff. The guy that did mine talked me into using fiberglass stuff and no rebar. I think it was a big mistake for me. But for you, being in sand it might work out just fine.
