Sadly, i'm losing my indoor parking at work and need to park my 08 drz 400sm on the street. i'm in san francisco, so i'm worried about the upcoming weather and want something that is waterproof. i'm thinking a Dowco Guardian Weatherall Cover (size large) is a good bet. I searched around the forms, and didn't notice a good answer, so i'm wondering if the experts here have any other suggestions. what do you use?
