Wilbury, it only needs to be a general description. I've seen suburbs, shows, open drive, Towns, day drive and all sorts of things.
Think of it this way, if you were trying to get out of the house and you were yelling out to the Mrs that you were going to the next suburb and ended up 600 km away, who really cares. Once you sign it off, its open for a days drive no matter where you end up.
Keep it simple and you'll understand it easy.
