Great Scott, Everett — Sail-In Cinema is taking us Back to the Future (PG, 1 hr 56 min) at Boxcar Park, with special guests from the Pacific Northwest DeLorean Club! Come early to check out the time machines before the only waterfront movie series in Snohomish County hits 88 mph. It’s free and family-friendly as always. Dress in layers and pack a blanket (it gets chilly on the waterfront at night), and please stick to blankets or low-back chairs so everyone can see the screen. Sailing in? There’s limited guest moorage at Guest Dock 7, first-come, first-served. Movie starts at 9 p.m. Presented by the Port of Everett and signature sponsor PND Engineers.
