Short vs. Tall Grass

I grew up in a country where the grass was short and strong;
The cows there liked to eat it and it kept them all year long.

Where I live today the grass is usually mighty tall;
It loses all its strength when summer turns to Fall.

And even in the best of times it isn't worth a lot
Although it grows quite well when summer days are long and hot.

The problem is it grows so tall because it's full of water
And it takes a mighty lot of it to feed the bovine daughter.

It's said that you can always take a cow from east to west
But, taking them the other way has never worked the best.

The cows back east have larger guts to handle this lush treat
It gives them the capacity to eat and eat and eat.

But, if you ship a cow from west to places way back east
They just can't seem to eat enough to get enough to eat.
