Thank you all so much for your great advice-- it helps us tremondously.
(we got no help from the nursery... the sales person told us that the
person who would be loading the sod into our "truck"(a 1984 VW rabbit
convertible) would tell us what to do... that person turned out to speak
no english and even with my spanish-- which is not bad-- his advice
amounted to, "water it"
