Next week: Veronica's total winnings

Finally found the time to do some important research.
Veronica of Road Rules Semester at Sea has now been on 6 of the 9 RR/RW challenges (10 if you count Road Rules All-Stars). She has been on two more specials than any other cast member. Her involvement began in season 3, back in '98, and then picked up again in season 5, the Battle of the Seasons, for all the following series (Battle of the Sexes, The Gauntlet, The Inferno, and the soon to air Battle of the Sexes 2). Mark from RR: Season 1 is Veronica's closest competition, appearing in 5 series, though only as a host in seasons 1 and 3. Mike and Coral from Real World 10: Back to New York have played in more seasons than anyone but Veronica, with a total of 4. Even players who seem ubiquitous, like Eric Nies and Theo, have only appeared in 4 and 3 specials respectively.
