I actually consider the word 'country' to be the biggest lie in the real estate biz. If the property's owner does not make his/her living off of that land, then it is not 'rural' or 'in the country'. It is nothing more than an urbanized area with very large lots (just my opinion, your's may vary).
Also, simply because a piece of land is or is not inside the corporate limits of a city or village does not determine whether or not it is 'rural' or 'urban'.
As you gain experience, you'll also start seeing instances where the residents of such areas start whining that "We moved out here into the *COUNTRY* to get away from this traffic and congestion and crime and yadda yadda yadda and NOW we're being surrounded by all of this development and traffic and congestion and crime, etc...

".
I'm seeing a lot of this big-lot urbanity around here, too. Often, I think of the owners as using their lawns and riding mowers as a primary way of measuring the very status of their 'manhood'. Also, when I drive around in those areas, I just can't help but to try to envision what they will be like 50 or 75 years into the future, as fuel prices become a bigger and bigger percentage of ones' expenses, the metro area continues to grow in population and economic activity and market forces have caused those areas to become functionally obsolete as they were developed.
