How many people can land support?

[bigpaul]

and where do you get your food from, your water? do you know anything about food growing, crop rotation, even what seed to use? what wood burn best? what wood is best for woodworking?
can you make your own clothes, your own footwear?
its all very well whooping it up but at some point reality will bite, what then?
I doubt you'll even get out of the city alive, not with all those low lifes and street gangs and drug dealers!
