(Portland, OR)  --  Teens from around the country are lending a helping hand in Portland.  Dozens from Washington, Idaho, Missouri and Oklahoma are helping to renovate established homeless camps in the city.  KGW reports the trip organized by Portland's Agape Church of Christ.  Yesterday, a group of 15 teenagers helped scrape old paint off the community center at Northeast Portland's Dignity Village.  It's an annual event, and this year the focus is on Portland's housing crisis.  The group hopes to have finished projects at numerous camps by next week, including repainting the exterior of Dignity Village's community center and replacing its roof.
