Neon lighting is still very popular around here. I haven't yet seen an LED neon replacement in an outdoor application. As for HPS, it's still seen sometimes in rural areas and parts of Hillsboro, but most of it has been replaced with LED. Many parking lots still use MH and sometimes HPS, though.
Still quite a bit of HPS on Bethany Boulevard and other places in Hillsboro I drive through regularly. I'd agree that neon is still common here, and probably will always be around in certain applications. It did slightly irritate me that they converted the old Burlingame Fred Meyer sign to LED when they restored it, but at least they did a good job of it.
