just to note, ron, yes its possible some people out there may be having bad trips due to laced mushrooms, but I have seen people have really bad trips on mushrooms we picked ourselves, cubensis in the cow fields, so it also does happen.. 

In any case, I agree that it is much better to pick (or growing your own) than buying. SWIM only bought mushrooms twice, once in amsterdam and once in a festival, and it didnt feel so right (not because they were fake, but just because SWIM doesnt like buying psychedelics, its a bad start somehow, IMO it contradicts with the whole purpouse of these substances). Picking/growing/planting/sharing is the way to go
