We caught those seagulls in full picnic-interrupting action at Alki this afternoon, just as we read a note from Lora Lewis at Hotwire Coffee (WSB sponsor) reminding one and all that the rescheduled West Seattle Movies on the Wall showing of “Finding Nemo” is this Thursday night — and we liked the seagulls in “Nemo” (video) even better than Nemo, Dory, et al. Remember to bring nonperishable food for West Seattle Food Bank and a few bucks for concessions (presented by West Seattle Christian Church and benefiting WSFB) plus fundraiser raffles – Lora says the prizes up for grabs so far include “four $25 gift cards from Pagliacci, a Sonic Care toothbrush from Dr. Wolff and 50 goldfish goodie bags, plus a hand painted table from WS Christian Pre-School.” (Later add: Free BBQ Pork Sliders from Dream Dinners [WSB sponsor], as well as — for the raffle — a $100 Dream Dinners gift certificate and a Dream Dinners Exclusive pitcher, tray and 6 beverage glasses.) The movie’s at dusk (we’d advise getting there no later than 8 pm); two days after this special Thursday showing, the final Sidewalk Cinema presentation is “Galaxy Quest” on Saturday night.
