In many parts of the Northeast, you don't even see too many white people at state parks during the summer months. These places have become dominated by immigrants from Latin America and Asia.
That's it right there. Black people aren't "outdoorsy" at all. From my "racist" experience of the past several decades, almost ZERO black people know how to swim.
I've never heard of black people hunting, fishing, camping, hiking, or doing anything in nature.
They hang out in the cities.
