RE: Fwd: Nitrogen application rates

There is nothing wrong with blue-grass music either.  I love to lay on the
blue grass and listen to the music of the wind while looking at what shapes
the clouds have made in the soft blue sky mid-summer.  (LOL)  O.K., I've
never REALLY grown up.  (No pun intended.)

Blessings,

Bonnie

Oh man, I love Blue Grass.  I just got an Alison Kraus cd.  She's quite
talented.
