Someone wanted that we go down to level 17 (I assumed the OSM grid). The data gets sparse at that level and 2/3 of the total requests are in that level.

Compare http://www.openstreetmap.org/?lat=39.76598&lon=-104.872&zoom=17&layers=M

The extent is limited to Denver, but I can extend that if we only seed till level 16 or 15.

From where do you count? Can you send me permalinks from openstreetmap.org?
