Murals are being painted over that tell the story of conflict and peace in Belfast - this original photo set tells the story, but look fast: these are disappearing every day, being slowly removed or replaced with neutral paint colors and advertisements.

DON'T blame the goalkeeper for failing to block a soccer ball with a spin on it. Likewise in baseball, it's not fair to trash the batter if he misses a curve ball.

The requested page title is invalid. It may be empty, contain unsupported characters, or include a non-local or incorrectly linked interwiki prefix. You may be able to locate the desired page by searching for its name (with interwiki prefix, if any) in the search box. One cause of this error is an attempt to load a URL such as http://en.wikipedia.org/wiki/| (the | character is not permitted in page titles). This error message is also displayed when a URL pointing to a "non-local" interwiki page is encountered. For example, the URL http://en.wikipedia.org/wiki/meatball:WikiPedia will give this error, because the "meatball:" interwiki prefix is not marked as local in the interwiki table. Certain interwiki prefixes are marked as local in the table. For example, the URL http://en.wikipedia.org/wiki/meta:Main_page can be used to load meta:Main_page. All interlanguage prefixes are marked as local, and thus URLs such as http://en.wikipedia.org/wiki/fr:Accueil will work as expected.Return to Main Page.
