I have been working 50 years for this. I hope I live long enough to see national prohibition ended!
Harbory is a good location (closest), and their staff is very helpful (although it has taken me several visits to get tips and product information.)
But the prices are TOO HIGH. My GREAT Fear is that, ultimately, GREED will drive people back to the "Black Market". If we don't get the tax and profit balance right, we will not eliminate the vibrant illicit market. Currently, Medical Cannabis prices are too high. I don't think this is unique to The Harbory - it's likely true all over the State of Illinois, and is from the legislature. More education is needed there for this to work long term.
