Eugene needs a new place to grind. That’s why Ninkasi Brewing’s Pints for a Cause benefit March 18 will support the proposed Washington-Jefferson Skatepark and Urban Plaza. The 23,000-square-foot, custom-designed skate terrain needs to raise a total of about $240,000 — luckily not all in one night — for the project, which will be built in the summer and fall. Pints for a Cause features music by dj foodstamp and Hot Milk, plus food by The Sandwich League. Check it out 5-9 pm Monday, March 18, at Ninkasi Brewing, 272 Van Buren St.
