Residents in four large metropolitan areas in California were interviewed by phone to determine differences in outdoor recreation participation in national forests by ethnoracial groups, age, and gender. The researchers found that the most listed constraint to participation among all groups was a lack of time, though minority respondents were more likely to list resource-related constraints such as lack of money and transportation.
