 Saturday morning's fire spread to nearby cars and even a home. Road crews in the Portland area shut down a major freeway over the weekend so they could clean up miles of graffiti. Well, less than 24 hours after the project was finished, the vandals have struck on 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. Don Hamilton with the Oregon Department of Transportation says they're working with state police to help discourage the vandalism.
