You know, some people need to realize that the internet is global. Nothing
wrong with going to the beach in January if you're in Australia. And
nothing wrong with planting grass in summer if you're in Greenland. Neither
you nor Probably know (because he didn't tell us) where the original poster
is or what zone he is in (if in the US). I'm in Minnesota, and although
it's not typical, the high here yesterday was 57 degrees F (14 Deg. C).
That's not too hot for planting grass.
