Suggestion: bring a big tote bag...just in case there's anything left in the place!

A thought...think outside the box! My husband and I were at the Dunes for the liquidation sale. We were able to remove signs from the walls. Not many people have something like that in their collections! (Bring a screwdriver!! I'm serious!)

And one more thought...one collectible that I LOVE is a room number plaque from one of the hotel rooms at the Frontier Hotel. A friend was able to acquire it for me... (It goes nicely with the peephole thingy that we got from the Dunes... )
