 So we look at a lot of access. We also look, there's a long history of kind of racial discrimination in this country. And so some minority groups have less access, don't feel as comfortable or safe in the parks. And we just had another paper come out that showed that the time that you spend in nature as a child is a significant predictor of the time you spend in nature as an adult. And so for those of us who didn't get much time in nature as a kid, it is overcoming some barriers as you get older.
