Everybody oughta get into the cow business at least once in their life.
Yep!
MM, I will say what everyone else has already mentioned. Unless you are willing to see the 2 acres get tromped all to hell I would pass on sticking any cattle on it.
As for distillers grain, 20 years ago my dad used to get rail cars full of the stuff. All I remember is that it smelled pretty good. He'd dump some in with the chopped hay in a mixer wagon and feed it to calves all Winter in our little feedlot.
