The geography of visitors

Here's an interesting breakdown of BWCA visitors by the home state of the trip leader (again averaged summers '03 & '04). The clear majority of permit holders are Minnesotans (59%), and most of the other visitors come from around the Midwest. But all 50 states are represented, as well as Canada and Puerto Rico. Notice the precipitous drop-off in visitors across the U.S.-Canada border -- the BWCA is really an American wilderness.

For these figures, I defined the South as Texas-Virginia, the Northeast as Pennsylvania-Maryland-D.C.-Maine, and the Midwest as North Dakota-Kansas-Missouri-Ohio. Gray = zero visitors in '03-'04.

Where do you fit on these figures? When I reserve BWCA permits, I use my parents' address in Minnesota, so I'm one of the crowd. I imagine this data is slightly skewed in favor of MN, since "in state" members of a multi-state group are probably more likely to assume the role of "trip leader", at least as far as making the permit reservation.
