Whidbey Island residents should expect to see a whole lotta hogs on the roads this weekend.

The 33rd annual Oyster Run is officially Sunday, Sept. 28. It’s the largest ‘cycle run in the Pacific Northwest, with motorcycles converging in downtown Anacortes from all directions.

The state Department of Transportation warns drivers to be on the lookout on roads for motorcycles in all shapes and sizes. The heaviest motorcycle traffic will likely be through Whidbey and State Highway 20 and Interstate 5 in Skagit.

“This is a free event,” the Oyster Run website says. “No time schedule. No required route. No official starting point. Pick your own route and Support Biker Friendly (businesses) along the way!”

El Cazador and Flyers Restaurants in Oak Harbor are among the businesses listed as being “biker friendly.” Whidbey Island Rollergirls will be entertaining everyone in downtown Anacortes, if the weather is right for outdoor rollerskating.
