In a recent game my Investigator was lucky enough to find the remains of a Proto-Shoggoth at the Graveyard and then a two toughnes "taxidermist's trick" at the Historical Society. The third stop was the Woods, where Sadie Sheldon offered me membership.
My fellow players urged me to save the monster trophies, but it'd been a long time since anyone had even had a chance to join the Sheldon Gang, and I thought it could bring enough advantage to be worth it. So I seized my chance to join and during the game tried to steal three times. Once I got nothing and the other two times I got $2.00 each. In the end that extra $4.00 proved vital to getting a coulple of Investigators back to Arkham and restoring one's sanity .
So has anyone else been particularly helped by joining the Gang?
