i've done a few in the states, never overseas. some are more legit 'farms' than others. one in maui was far from self sufficient but i planted so many pineapple crowns that today it may turn a profit but we didn't have enough diverse crops to live off of.
worked on another in carnation, wa that was the dope show. worked a lot more hours [40ish vs 20ish] but it was a real farm, over 100 acres in a small town w/ hefeweizen beer in the dumpster!
i skated some mannies and rode bikes past emus while there. town wasn't much but then on the wkends we could borrow a work van, skate seattle.
it was dece but i was fulltime alcoholic.
read reviews i guess is the best cause huelo lookout in maui was a piece of shit but full circle in washington was the dope show but i only know in retrospect.
not much but the WA one paid $100 or so a month [dozen yrs ago] and i've found other work trades that paid in maui but not through wwoof.
