Parks make visible both our attempts to rework nature, and the incomplete fulfillment of those attempts. Over the plannerly concerns of landscape architects, parks contain the traces of what came before the land was park, and the traces of what will come after. In these spaces I see human designs upon the land overcome by a cacophony of living beings vying for space and control. If fields promise leisure, so do they also threaten isolation and danger, especially in darkness, and from behind the veils of overgrowth at their margins. If we would use parks to reclaim undevelopable or disused sites for play, so do the brambles and vines reclaim the trails and fields for their own ends.
