Field vs. Pasture

Tricia read my blog, and has this to add (and opted not to put it as a comment, I guess...):

This is the farm girl talking....... A field is a piece of ground that has been or will be, with the intent, tilled for the purpose of growing a busheled or measurable crop.
A pasture is a piece of ground that is grassy, and may or may not have been sowed withsome type of specific seed, with the intent to graze animals (put out to pasture), or propagate the seed sowed.
The piece of ground you refer to is most likely an overgrown lot, unless it
is the Stewart's land you refer too, and that is a pasture, or at least was when we were kids.

So there you have it, folks. However, it was always referred to as "Opal Palmer's Pasture" (I've since remembered it was referred to as a "pasture"), which makes me wonder if at some point she didn't keep some sort of animals there. I know there was a fence at one end of it, so maybe she did at one point.
