A couple of months ago I mention that Kent Mathieu (Taipei Air Station blog and website) has been posting videos to YouTube of his walks around Taipei. He has now done several of these videos, pointing out where things are (or used to be) located. The most recent video (30 Sep 2010) is a walk along Sung Shan North road in the vicinity of the hostels and HSA compounds.
You can find his videos HERE, and I've also added an item under "Taiwan Links of Interest" in the right-hand column of this blog. Look for "Kent Mathieu's walking tours of present-day Taipei."
