Here's an listing from Orlando's Craigslist referring to: "Don't be fooled by muck based sod". http://orlando.craigslist.org/grd/2261250135.html I've asked experts and others in the business and I just don't see how one (sand based) is clearly inferior or better than the other (muck). Like myself, others have opinions but is any of it really research based? I'd love someone to provide some solid facts/evidence. Otherwise, I want to call out someone that wants to advertise that one is worse than the other. Yeah, "don't be fooled" or rather I won't be, since I'll be calling the people of www.FloridaTurfPro.net to see if they can convince me.
