When I used to live in ca, there were plenty of walk-in style parlors offering massage. I don't see that there appear to be any in all of Oregon... Is this true? If no, how do I find them?

Not like in CA or NY, at least. We have "lingerie modeling" places, known as "jack shacks" because they were largely self service "shows." With the down economy, some of these reportedly have loosened their standards. But massage is done by FSBM and FSBM+ girls who have their own incalls and/or who offer outcall.
