The best way to get replies from people in your local area is to post in the discussion thread designated for your local market. At the top of the "Local HDTV Info and Reception" forum, there is a section called "Sticky Threads". One of the sticky threads is the thread index for the U.S.
Here is a direct link to that thread.
Portland is the #22 market in that list. There are also lists for each state.
