Got a call telling me I had won one of four quite appealing prizes, new car, money, TV, etc...but that I had to go in person and listen to a 90 minute presentation. Was given a claim number, and an address:
Global Destinations
18342 W Creek Drive
Tinley Park, Ill
60477
Also, some moderate pressure, they would then go on to runner-up if I couldn't make it, etc.
