ARTrails is an event where artists open their studios/workspaces to the public. You can drive around the countryside to visit them this weekend and next.
I prefer to go to the opening. There are usually appetizers, and each artist has one piece of art displayed. You can often meet and talk to the artists. The event begins at four but I will be there at five.
McMenamins is just around the corner from the train station if you want to make more of an evening of it.
