The commute from Lake O to Portland is kind of lame: up I-5 through the Terwilliger Curves-can be a nightmare if there's an accident-or up OR 43, which can be slow in rush hour also. TriMet does provide service from Lake Oswego to Portland and also a few express buses at rush hour, which are supposedly quite crowded.
