Name one, just one that you have 100% confirmed and not speculated.
As far as the banks have been allowed, it's to open accounts for the businesses. Most loans have come from private investors at this time. See also: arcview.
No banks are intentionally or directly lending to MJ businesses. None will until federal penalties are a non issue...the banking provision allowed banks to open deposit accounts, whether it not they will is their choice. I wouldn't imagine anyone other than state chartered Colorado Banks having much interest currently.
