The nearest airport is Vancouver International Airport (YVR), which is about a thirty-minute taxi ride from campus, or about an hour on transit.
Another option is to fly into Seattle, about a four-hour drive away, although the border crossing can add considerably to the trip time (depending how busy it is).
Vancouver can also be reached via Amtrak. The train ride up the coast is beautiful.
We are hosting a carpool blog for any VSPC participants who'd like to co-ordinate among themselves to drive from a nearby airport, to get around town, and/or to explore the area around Vancouver, during the conference.
