Just archived West Side Story (GC5FBD) a few minutes ago after returning from the site. The following note was posted to the cache page:

Sad to say, this cache lasted about as long as Bernardo did in the "rumble" at the end of Act I of West Side Story.

We went back to check. Team Sand Dollar was right. Live theater is one thing; live caches are something else altogether. We should have checked more carefully when we hid it.

The cache has been physically removed. Apologies to anyone affected by this.

Thanks, Loran, for catching us on this.
