I live in Downtown Calgary, so I'm definitely familiar with not leaving anything worth stealing in my car. A friend of mine had his car broken into for a snickers bar an some change one time.
Anyway, there's a lot behind the hostel, but unfortunately i'm going to have to pay market rates to park there as I'm there during the week. How much is parking in Seattle?
