The Portrait Gallery goes for the gold...errr...platinum.

So I went to the National Portrait Gallery the other day and saw the Mask of Lincoln exhibit they currently have going on there.

As amazing as it is to see 160 year old photos of Lincoln, a random thing happened. When my friend and I entered the gallery, we saw this...
My friend and I proceeded to use her precious anytime minutes to have our very own audio tour of the entire exhibit. Especially interesting was when the security person came in and told us we couldn't talk on the phone and I, embarassed, pointed to this sign. We finished our (audio) tour and mused about the coolness of audio tours via cell phone. Platinum...I think yes.
