In regards to mg's earlier request for carpooling, I've posted the following on the PTMF web site:
We encourage people to carpool and share rides to come here. For people in Vancouver, and even Seattle, this can be a way to share gas costs, help the environment, and perhaps even make it possible for someone to come who could not otherwise afford it. If you have extra space in your car and would like to be helpful in this regard, please send a note to firstname.lastname@example.org and we will try to coordinate people. Those offering a ride will be given the e-mail address of those needing one. There is no obligation to PTMF and you make your own decisions and arrangements.
