I'm sure glad I live in the states but we don't have any square kilometers here, much less hectares.
I happen to live about twenty miles or a little less from the White House. Yet just a few miles from the house in one direction or another are one lane bridges, log houses (old ones, too) and a fair amount of woodland. But don't get me wrong, there is plenty of development and the open spaces (and woodland) are fast disappearing. At the same time, there is resistance to what is locally called "infilling," which is new construction of vacant city lots. It is funny when I recall how people complained in my home town in West Virginia (think Northumberland), which had fewer than 10,000 people, about the traffic and lack of parking.
So, there is a lot of new development further out. The city is ringed by circles of suburbs. People are commuting as much as 75 miles one way to work, mostly by car.
I live in what you might call the second rind of suburbs and am lucky to have a lot of woods and parks near home. There is no building on a lot of land in my neighborhood because it is designated as "flood plain." It is actually a long way from being a flood plain but the better land for building homes was used up a long time ago when there was still a real Lord Fairfax living here. The Lord Fairfax I am referring to was the last peer living in Virginia, as far as I know, and his estate was near Front Royal, which I referred to in another post this morning. It is outside the northern end of Shenandoah Park, where I have most of my outings.
The woods near my house have a lot of wildlife, short of bears and lions, though bears have been spotted in the county. There are foxes, deer, beaver and groundhogs, not to mention squirrels and rabbits. Sooner or later there will be coyotes here but I doubt wolves will be here anytime soon. It provides a good place to try out hiking and camping ideas, and to keep in shape by carrying a pack over a realistic trail. It wouldn't be a good place to have a fire but you could easily try your hand at shelter building.
The only thing is, it can be a little boring to visit the same nearby place too often, since one of my chief interests in the outdoors is simply to go down a trail I've never visited before.
