This isn't Minnesota or Ontario or New England, where skating rinks rival movie theaters and bowling alleys in quantity and attendance. And it's not New York City, where seasonal outdoor rinks at Rockefeller Center and in Central Park offer cinematic backdrops. Some of the spots where a young Tonya Harding practiced her first jumps no longer exist, like the old rinks at Clackamas Town Center and Jantzen Beach. But Portlanders do still have options, including places that offer stick-and-puck time, hockey rec leagues, and beginners' lessons.
