There is public transportation around the Portland area and Forest Grove. You could definitely get from the airport and around without a car if you don't mind some walking. We can try to arrange as much car pooling as possible for any trips outside the local area. The trip to the coast would be the one that would be the hardest to do without a car. You can plan your routes here: https://trimet.org/home/planner The red line westbound max train runs from the airport to Hillsboro transit center. It would be pretty easy for one of the local folks to pick people up from there. Please reach out to Ariel if you have any questions about public transportation.
