Crosmando: What's the bet that those people would quickly return to urban life once they realize just how hard rural life is.
I for one am very thankful I don't have to farm anymore. I'd encourage anyone who wants to do it to at least work on a farm as a hand for a while to see if it suits you. If I was able to farm as a hobby, that might be one thing (even though I wouldn't be too much into that) - but I'd only be able to do that because I got a better paying job in the city and had saved up and could afford to farm as a hobby. To me the reality of living on an operating farm for a living, especially now that I'm older, is not particularly appealing, especially considering how expensive farms are to purchase in the first place.
I'm having flashbacks of muddy shoes/boots, gummed up hands, heat, and the constant time demands (forget a weekend trip to anywhere). There are probably innovative time-saving approaches now that just weren't around when I was growing up on a farm, and those are interesting to me (something like hydroponics, or greenhouses), but that's not what I think of when I think of farming. I think of cows getting out, fixing fences, a foot of snow on ground and hauling hay back to the cattle, cutting and splitting so much wood (it's amazing how much wood it takes to stay warm), hours in the heat cutting hay/working in tobacco, planting/harvesting crops, broken machinery that needs repairs, lots of mud and cow poop ;-), and just the constancy of all of it - you never really look forward to anything different. If someone loves it, it might be great, but it probably takes a special type of person that really wants to do it.
