I live in Newcastle Bill, which is just north of Renton off I-5. It is 130 miles from my house to the Mission front gate, and I usually make it up there in 2.5 hours with normal traffic. You'll be at least 25 minutes closer from the Edmonds ferry dock, minus the time to takes you to get from there to the freeway. So your commute should be shorter than mine from that point, but you never know what to expect at the border. The best route is off at Bellingham and over to Sumas, then it's a 10 to 15 minute drive to the track from there. If we go up mid day on a Friday, or real early on Saturday the wait is typically 10 minutes or less; the wait coming home is usually much longer.
