I am wondering how easy it is to find players if I want to run a pickup game. I have some Cthulhu scenarios that I enjoy running and players have had fun with in the past. I plan on having the materials with me and ready to go, but I am somewhat concerned about finding people to play. I know Cthulhu games tend to fill up fast for cons (see GenCon for example where they are sold out basically as soon as people hit the register button). Any help is appreciated.
