You may take a second shot on any shot; including the putt. In fact, the putt is often the best choice. Do not know why it's called Cali. Perhaps because this was one of the first states representing disc; and they came up with the first good way to play with odd number of individuals.
Wolf is a very good five person game.... Order of players is selected through flip. Order remains the same throughout round. Player #1 tees first on first hole. He then picks a "partner" as the others throw. He must choose a partner after the player drives; but, before next player throws. Original driver (in this case, player #1), and his "pick" play the remainder of the hole together; against the other three. Second hole, player #2 leads off, with player #1 throwing last. If no one is chosen, the last player to throw becomes partner by default. Scoring is determined by "skins" won. I would recommend playing for a quarter or less, per skin; or wolf can get quite expensive. Driving player may also call wolf; after his initial drive; however, ties go to the rest of the field; and therefore wolf is really never called; unless an ace is hit. Perhaps a park job on a very long hole; if one knew the rest of the group were noodle arms!!
