(Portland, OR)  --  Numerous potholes are a by-product of the recent storms that swept through the Portland area, and transportation officials say they'll get a "patch-a-thon" underway today.  Transportation commissioner Dan Saltzman will get the process started when he fills in a pothole this morning.  Brady says the patch-a-thon will continue until the pothole backlog is cleared.  PBOT says it fills more than eight-thousand potholes each year in Portland.
