What Sajhamitra says.
Not a crazy idea, or not a novel idea at all. There are hoards of businesses already in Washington/CO area who have either already setup a business or are going to setup one. Since Obama administration has said that they won't pursue against these business even though Fed bans it, banks are not loaning businesses any money for this venture. Hence the only limit is that you have to cough up your own money. I guess there still money to be made there, but it is not a new/crazy idea by any means.
