 The fire Saturday morning spread to nearby cars and even one other home. Road crews in the Portland area shut down a major freeway over the weekend so they could clean up miles of graffiti. But less than 24 hours after the project was completed, the vandals struck I-84 again. This is a problem. Everybody in the community knows graffiti and litter are a problem in the I-84 corridor and in many places around the community.
