    // ... get the annotation delegate and allocate the MKAnnotationView (annView)
    if ([annotationDelegate.type localizedCaseInsensitiveCompare:@"NeedsBluePin"] == NSOrderedSame)
    {
        UIImage * image = [UIImage imageNamed:@"blue_pin.png"];
        UIImageView *imageView = [[[UIImageView alloc] initWithImage:image] autorelease];
        [annView addSubview:imageView];
    }
