I grew up in an area of the country (central Illinois), that had wild hemp growing along lots of railroad tracks (one year, the town kids set up a 12-footer in the 'town square', and put Christmas ornaments on it, ) ... anyway, as memory serves me, it didn't look any different than most sativas, tall and lanky ... but, smoking a pound of it wouldn't get a fly high ... in your situation, I would guess someone planted MJ there as a prank ... :smokin:
