No one from Evergreen ever brought up 500K - we couldn't, there aren't even that many mountain bikers in the region!  The estimate referenced for Duthie Hill is between 150-200K/yr.  But Duthie is a one-of-a-kind bike-only park; a very different situation than what is being proposed for the Lord hill Master Plan.  Growth of riding at Lord Hill park will be commensurate to the County growth and the number of mountain bikes in garages.
