No, I'm not actually.
Yes it might be possible to see that far,
but that assumes relatively flat and open terrain. I grew up on 200 acres - a fairly small block really, but there was no way you could see from one end to the other because of the ridgelines, forested areas, etc. It was often impossible to even hear gunfire from some points.
Additionally, the idea is to meet any threats well away from your boundaries if at all possible. You'd want to extend your patrols several miles in all directions.
If you're dealing with bandits within your boundary, you've got major problems.
Now, if your land is on nice flat ground with clear sight lines for miles, then a simple watchtower might well suffice. Problem with that is sight lines are two directional.
In the initial stages while the characters are learning the how of farming, as I mentioned earlier, it's far better they focus on small area subsistence farming with an emphasis on concealment and protection. As their skills and resources improve (scavenged machinery, seed stock, additional personnel, etc) they can expand their cultivated area, always however with security as a background thought - even several years post nuke there's still a lot of starving people willing and able to do nasty things to get a meal.
