On Saturday, Sept. 8, at noon, local skateboarders who frequent Alameda’s Cityview Skatepark, 1177 W. Red Line Ave., will host the fourth annual “Land or Slam Skate Jam” fundraiser there in memory of the late Clay Harding, an Alameda skateboarder who lost his life in 2014. The event is free, open to all ages and features barbecue, local art and music and a skateboarding contest. Prizes donated by local skate shops will be given in three age categories. Registration for the contest starts at 11 a.m. with a $5 entry fee. All proceeds from the event will benefit the skatepark.
