"Do you have an idea of how crowded the train would typically be at rush hour from Goose Hollow to Intel?"
The train is not very crowded in the morning. It's not empty, but hardly a sardine can. And going back into town is not bad unless there is a Trail Blazers game going on that night or something.
I do agree with Greg that the area around Intel is just suburbia. Things are very spread out there and not very walkable like downtown would be. I have long thought about moving out that way as that is where the jobs are and may one day, but right now I like the city too much.
