I heard a funny story this winter. A local pothead was out snowmobiling a few yrs back, going by a slough when he saw a big patch of MJ growing in it! Apparently his first thought was "I didn't plant that!"... then he realized he did try growing it there yrs previous. Apparently the seeds didn't germinate that 1st yr, but did after and grew themselves into quite a patch! In the middle of winter, they were all freeze dried etc, ready for consumption!

Next yr might grow a field of hemp (certified organic). Not as good money as the other I am guessing, but less legal hassles, tho you do need a criminal background checka nd they can search your field for illegal plants.
