I'm in Oregon. Ruling varies from area to area. I'm in Deadwood Oregon where you do what you want. Except for me,and I ain't talkin, there are three types of folks here: Dope growers,Baptists, and those that are both but won't admit to it!!
Kidding aside,all of the smiths I know are outside of city limits and nobody has said a thing. Log on to NWBA site where most Oregon and Washington smiths hang out and ask the question there!
Feel free to contact me at: spradoeric@gmail.com or phone 541 964 3224. I can introduce you to local metal smackers.
