riddle - Four Directions #4 - Where and what am I?

To the North a dusty foot philosopher was born
To the South as you go, the colder the weather

To the West is a brown leaf - wait is that a horn?
To the East is a place to get back together

I'm with a group of fellow ghosts hanging out at the park. Where and what am I?

Four Directions #1
Four Directions #2
Four Directions #3
