Call came from a familiar area code and prefix which I recognized as an AT&T cell #. When I answered I heard a recording "from Expedia" telling me I had been randomly chosen and had won a free vacation. I was then asked to hold. A real person came on the line and started with the whole spiel again. I hung up. I did a search with WhitePages.com and found that the number appeared to be coming from the downtown post office. I'll be doing an online report at us.gov as well.
