The better options around Portland for placing gear or top roping that I know of are The Far Side, Ozone, Beacon, Salmon River Slab, Frenches, Broughtons, and so on Its pretty hard to set top ropes in many places if you are not prepared to lead, then you will need to stick clip your way up or rope in to the anchors. If you are going to Smith, the best option for top roping on the tuff is Rope a Dope block.
I have PRC 3 which includes all those except The Far Side. Is there a link to how to get there, routes, etc?
