Many years ago I used to try to purchase seed for it (as an interesting cactus/plant to grow), as it was listed in a popular seed catalog. Unfortunately, they wouldn't send it to me (good ol' USA!), however it was listed... as the same catalog was being sent out to Canada and other countries too.
I remember seeing an interview a reporter did with a guy sitting in a bar in Amsterdam, with a drink and a "smoke", etc... and the interviewer said to him, "Do you realize that if you lived in the United States that you could be arrested for what you are doing here!" The guy looked at him a moment and said, "Well, why would you want to live there?"
All I thought was...Good question! Yea, land of the "free", home of the gullible! (Have you looked lately, even what IS free... isn't free!)
Used to be that folks had common sense to guide them, not more laws!
Interesting links dvg. Makes me wish I lived further north. The cold gets to me however, as the winter season is long enough in the mid-west as it is!
