Ian Cooper writes:    I went for a productive photo shoot at Colquitz River Park in Saanich and the Galloping Goose Trail in View Royal late last night, before and after midnight. The weather forecast called for ‘Rain overnight’ but I was out for four hours and didn’t get rained on at all the whole time – not even spitting drizzle on my way back.

Ian Cooper writes:  I made a point of riding to Colquitz River Park and View Royal for a photoshoot overnight to ‘seize the opportunity’ to take pictures ahead of the approaching windstorm that’s expected to wreak havoc later today and Wednesday. Despite the forecast calling for 60% showers and donning my raingear, I wasn’t rained on at all over the entire 4 1/2 hour outing, although it had obviously showered before I left James Bay out around 2:30 am. It was cool out; there was frost on the Selkirk Trestle on the way to Colquitz, but I was well insulated with multiple layers.

All pictures are from my overnight photo shoot at *Colquitz River Park and # View Royal on November 19.
