(Portland, OR)  --  The Multnomah County Sheriff's Office conducted a speed racing mission in the Columbia River Gorge on Saturday.  This follows several reports of speeding and racing drivers.  Earlier this month, a speeding driver crashed down a 150-foot ravine.  On Saturday, a motorcyclist tried to elude deputies and crashed.  The rider ran into the woods, but eventually surrendered.  He was treated for injuries and charged with felony and misdemeanor elude.  Other drivers were cited for speeding and deputies cleared the Crown Point parking lot where illegal street takeovers have happened in the past.
