There are various reasons to close a thread. Sometimes it becomes too long and it's more expedient to begin a new one. It makes it much easier to browse the posts. Sometimes a thread strays so far from the original topic, it no longer has continuity. In that case, it's just best to start over.
In this particular case, I felt that the thread had run it's course and was bordering on the argumentative. I saw no constructive purpose for it to continue, so I locked it. Did I do it too soon? Was it really necessary? I'm not sure, it's a judgment call. I let many things go that are borderline, but I guess I just chose to act on this one. My intent was not to spoil anyone's fun. :winking:
Please don't see it as censorship, but rather a means of keeping things on track. This happens rarely and if you noticed, the original photo was reposted by Musketman and a conversation has ensued.
