The MAX in Zero Effect
The part I love most about Portland is the MAX, the city's street level light-rail system connecting the suburbs with the downtown core. I've only riden it once from the suburbs—during my friend's bachelor party—so most of the times are from and to a point inside downtown Portland to somewhere just outside the core. This year, while at a week-long conference, I took either the Red Line or the Blue Line train to the Oregon Convention Center from my downtown hotel, since, well, it was free to do so.

A couple of weeks ago, I watched Zero Effect, set in Portland. The movie is primarily about a timber tycoon who is blackmailed and is given elaborate directions to drop payments each time. During one of the payments, the tycoon is directed to hop on a MAX train (though to my recollection, it's never reffered to as "the MAX" but as "the train"). I just edited the Wikipedia page for the MAX to include information about that reference, since other appearances in film of the MAX were listed. It's my first major contribution to the Wikipedia, so I expect it to be edited—it could maybe use a little more detail—I'll save for a little posterity the text that I wrote:
Zero Effect (1998, dir. Jake Kasdan): the wealthy blackmailed timber tycoon is directed by his blackmailer to board the train with a three-digit number delivered to his pager while on his way to deliver his next payment. A MAX train, with the painted number 119 and "Portland" displayed on its sign, pulls up to him. He is then shown on the train for about 15 seconds. As the movie is set in Portland, MAX train bells can be heard in the background throughout.
