I live in the artificial turf capital of the world, San Diego.  There are more turf companies per capital  in this town than any in the U.S.  With that said, I found a true manufacturer of artificial turf with a dealer here in San Diego.  This manufacturer named Global Syn Turf is one the largest in the world and offer a True Manufacturer's Warranty.  If you need turf or an installer referral call Global Syn Turf and one of their dealers today.  Thanks for your service.
