With Measure 91 passing to legalize recreational marijuana in Oregon, city and county officials will now be wrestling with what they should do to prepare.  Hood River County Commissioners will discuss it at a meeting this evening.  Both County Administrator David Meriwether and Commission Chair Ron Rivers say local governments will be looking for guidance from both the Legislature and the Oregon Liquor Control Commission as specific rules are put together.  Meriwether notes cities and counties will want input into what state officials do.  Commissioners last month decided not to adopt a tax on recreational marijuana, something other cities and counties had done in an attempt to beat a clause in the measure limiting taxing authority to the state.
