I admit I am not too sure about the otcexchange.info yet until I see income producing features.
When I mentioned the 10 acre marijuana farm for sale posted from last month on Craigslist the seller indicated several things about the property and that it can be bought for $4000 down, total price of $55k for 10 acres. No current crop but zoning okay for marijuana.
My math would say this is their best bet for an easy entrance into mmj.
