There's a lot of wild hemp growing in the Midwestern US. Alot of it is along the railroad tracks and has been growing there wild since the Civil War era when tey used the hemp plants for making rope. Basically...the harvested hemp plants were transported via trains..and the seeds fell of and sprouted along the tracks. Where I grew up in Missouri (eastern KC) there was a road where it grew 15 ft high every summer on each side of the road for about 5 miles...

good for a headache..and nothing more. OK..fun to look at too....

good luck
