Oh no! You beat me to the punch! I was gonna post this cause I was interested in what Hubski's entrepreneurs and trend analysts thought. I guess I'll just leave this here . . .
I was going to recommend WWOOF to you but apparently I already did 11 months ago. Farming is hard work. For a lot of people it's rewarding. My grandfather loved his plot. Me? I put in raised beds and my wife and kid plant a bunch of stuff but then they ignore it the entire summer while I'm gone so I get to see the the "what might have been" harvest every year. Dunno. I got at least 3 cups of onions this year... and holy shit, pull your parsnips when they're young or they turn into Triffids.
Seconded on WWOOF'ing. A hard working frieend of mine from my synagogue fell in love with working with goats the last time she WWOOF'd between semesters. After either finishing up or taking a break form college, she's gone right back into the system on a new farm that she's been in contact locally. The system and choice it allows has got me considering it as an option out of graduation for a bit. Would be nice to use Taglit to get time on a kibbutz to compare the environments.
