PICNIC CHIC Fancy an afternoon of free-wheeling whimsy, complete with glamour nibblies and a saucy frock? That’s right Posh Spice—it’s picnic time. And whether your backdrop is West Van’s Lighthouse Park, Dr. Sun Yat Sen Chinese Garden downtown or the shores at Spanish Banks, a chic-picnic in Vancouver is a right of passage (along with owning a Sigg thermos and organic bug spray, both of which might come in handy for this mission). Ready? Set? Chill! Susie Wall
