About the grass ... I think last week they said people on the staff were doing the hand-picking. Wouldn't they maybe have some special grass patches or a grass farm in concert with the ag school? Or *is* there an ag school at Penn?
I was picturing something like wheatgrass that they put in health food smoothees (yecch) or oatgrass - some tallgrass of some kind. Or, whatever raw stuff they make hay out of, I guess, except for alfalfa, because they name that separately.
Anyway, by hand-picked, I assumed it was pulled up by the roots, thus eliminating any worry about the "cut" conditions or drying out.
Hah - what do I know?
Well the horse wouldn't like it with the root on it.
They probably just give them enough that they eat it right away.
