Nope - Arapahoe County.
The southern CC Trail (Parker area) is in Douglas and Arapahoe Counties. It is finished through Douglas, and hop scotched through Arapahoe.
Been around here since 1962 - sort of know the area.
Right now they are working a bot on the trail just north of Arapahoe Road. It is finished - a portion, at least - to just south of the Arapahoe bridge over Cherry Creekm near the new 24 hour fitness.
