Better to leave it out to get soaked, then blown dry, than leaving it to stay wet for a week in a garage. A good compromise is a car port - keeps the worst of the rain off, but leaves it open to the wind. Bizarrely, a heated garage is supposedly bad too - something to do with making the moisture evaporate up into places it hadn't naturally risen into. What you really want is a garage with a hefty dehumidifier!
Best of all is not to get it wet in the first place!
