The trail running along the Greenbelt has an interesting history. For example, the last section, called "The Hill of Life" used to be closed. John Hartman orchestrated a meeting with the Parks and Rec board to get the trail on it opened. The residents in the subdivision at the top of the hill had cut a deal with Parks & Rec to keep it closed; Hartman turned up at least 10 major neighborhood groups to argue against the special deal and prevailed.
