There will be a little more information next month, when the results of a survey conducted by Jerrell Richer, a professor of economics at Cal State San Bernardino, who recently cut back his work at the university to devote more time to the project, will be available. The survey, which asked forest visitors their feelings about the Adventure Pass program, also factors in data on income and ethnicity. But the survey's conclusions should be received with at least some degree of skepticism: Half of Richer's funding comes from the Forest Service. And the polling will provide no data about changes in forest visitation before and after the fee program was imposed. If the Adventure Pass has been keeping people out of the forest, there's no way to count the missing faces.
