On my trip to Portland last week, while my girlfriend went to the People's Farmer's Market, I took a jaunt over to the airport from downtown. To travel from the airport from downtown, I had to get a zone upgrade, because the 7-day pass we bought (see below) afforded us 2 zones. (We mostly traveled from Zone 2 through Zone 1 to the Fareless Square.) The fine folks at the TriMet information office at Pioneer Courthouse Square advised me that to get the zone upgrade, I would have to step on a bus, get an upgrade, and immediately disembark and hop on the train. I wasn't interested in risking getting caught by a fare inspector, so I made the trip to Gateway/Northeast 99th Avenue TC, hopped off the train, and got a zone upgrade from the #19 bus driver there.
On the trip I took quite a bit of HD video using the Flip Mino HD camera we bought. Following is a Hillsboro-bound MAX train arriving at Gateway/Northeast 99th Avenue Transit Center (which I will refer to in conversation as "Gateway" after the SkyTrain station here in Greater Vancouver).
Having a 7-day pass may not have been worth it from a purely financial perspective: as mentioned, we spent 5 days there in total and the pass did not apply to the Aerial Tram up to OHSU. (We would have appreciated a ticket stub as a memento of that trip. I sent a note to TriMet directly with that suggestion.) We did very much appreciate the convenience of the two-zone fare and not only the convenience of not having to fish for change, but being able to select which consecutive 7 days we could use the pass. In Toronto, you can't select which days. At least they have one, though: we'd love to be able to have weekly passes in Vancouver!
