(Portland, OR)  --  A bunch of military ships are arriving at the downtown Portland waterfront for the Rose Festival's Fleet Week.  Ships belonging to the U.S. Navy and Coast Guard plus the Royal Canadian Navy made port yesterday and more ships are expected today.  The gathering celebrates military service members and veterans, and some ships will be open for public tours throughout the weekend.  Those planning to tour the vessels should be prepared to go through airport-like screening and have a photo ID.
