totally wish i could help dude but i cant :(
idea for you though:
depending on how much stuff you have, you could ride our light rail here called the MAX all the way out to a town called gresham (not to sure how familiar you are with this area) but there will be a transfer between lines so here is how you would get from the airport to there (there is a stop at the airport)
next. once you get to gresham transit center you have to get on a bus system called the SAM(sandy area metro) sandy is another po dunk down up here on hood. that runs about every half hour on weekdays.
your going to want to get off at the stop at the very end of sandy, its going to be by a post office and an assisted living facility called avemere. the street right next to it is called langsted(spelling may be wrong) or you can just ask the driver to tell you when the last stop is, their usually pretty nice.
next. you have two options:
1. thumb it. walk out twards the high way, you can ask someone how to walk out there its only about a block. even if you have a ski bag that isnt an uncommen thing to see out here.
2. you can wait and take the mountain express. this costs about 2 bucks.and the SAM driver should have a scedual on the bus. only runs about every two hours though. and only runs till 6. if you were to choose this you could get as far as rhody, and then you would still have to hitch up to govy. upside to this choice is that when you ride upto govy if you get picked up about 95% of the time the person will be going atleast to govy.
after that. go bumbin around govy, stop by the bars, and you can prolly find somewhere to stay. if not, find a dry place(there actually are some in oregon) and bundle up tight!
i really hope this can help you out and good luck man! see you on the hill :)
