I haven't heard back from the woman who saw "people competing in the amazing race" at the Philadelphia airport, but now I believe that she probably did see TAR Australia. Why? More sightings yesterday, from Las Vegas!

I figured that they were looking for the Liberace museum. However, Wikipedia says the Liberace museum closed in 2010. It is in Paradise, NV where the tweets came from.
Update:
I found that one of Liberace's cars is on display at the Cosmopolitan Hotel on the Las Vegas Strip. I don't
know where they were seen but Paradise is a couple of miles (or more) away on the east side of the airport.
