Searching for a Lost Jungle in the City

The city is mysterious, a grid
Of paths, most of them laid wonderfully straight
Upon which brave explorers roam, well-armed
Against the strange and hostile denizens

How curious to leave a jungle known
And go in search of a jungle not known
Predicated upon legends and yarns
Lost forever in a tangle of dreams

Among the still uncharted traffic lights
In a gridded city of mystery
