Ambitious, glad to see this in Dallas. Urban parks are great, all cities should have them.

The best are usually those left to be in their natural state, Phoenix South Mountains, Foothills in Los Altos, and Sanitas and the Flatirons in Boulder are good examples. Takes a lot of foresight to leave a large swath of land undeveloped though.

This is fantastic! I'm looking forward to following this projects progress. I lived in Dallas for a while and loved the way the city integrates green space into the urban landscape. I'm not surprised that Dallas would be the city to take on a project of this scope.
