My first thought is how many people would practically kill for a driveway with a view that includes 800 feet of open field on one side. ;^) Is the field not kept up, or does it look out over unattractive farm buildings?

My second thought is that having to allow a tractor/combine or other farm machinery room to manuver, it might be easier to spice up the tree lined side with assorted shrubs tucked in here and there that flower at different times of the year, or offer fruits or colorful fall foliage. Not sure what zone you're in, so I can't really suggest anything specific, but some of the native vibirnums might be nice as they have multiple season interest; good scent, pretty flowers, nice fall foliage, and berries for the birds.

Before you plant anything, you'd need to find out from the farmer what kind of herbicides he's using. Unless he's fully organic, he's using them.

littledog, you're right about the benefits of having such open space. It is kind of neat driving next to a wall of corn later in the season. Otherwise, the view looks out over the field to distant woods. We're not committed to doing anything on the field side. Of course, our outlook might change if and when a subdivision takes over the field.

laceyvail, that' an excellent point about herbicides. Perhaps even as they relate to impact on the existing tree line on the other side of the road.

It's probably best for us just to periodically mow the weeds on the skinny strip next to the field and figure out how to spruce up the tree line without going overboard.

don't forget that some farming equipment might have a swing radius or turning radius, which may take out your plantings if the farmer is not aware of them.
