What's the buffer around a liquor store or a bar?  

The  intent of I-502 was to regulate cannabis like alcohol. A lot of voters bought into that. But it's taking far too long for some local governments to adjust to the "regulate like alcohol" thinking. 

Port Townsend used to be thought of as a progressive city. But it's way behind the cities in Clallam County when it comes to cannabis, for reasons I don't understand.
