These new USGS GeoPDF quads are awesome, but... useless. Most of them do not have trails, secondary (dirt) roads and even forest coverage. These new Colorado sets apparently have trails in national forests, but a sample I looked at (Longs Peak quad in RMNP) had no trails still.

Since it's outdoorsmen that use these maps, having no trails makes them worthless.

Here's what I do. Go to the USGS store and download older maps in (georeferenced) raster PDF format. These are hi res scans of real USGS quad maps. Just pick up anything older than 2012/2013. Use Acroread to print each map in poster mode 75% scale landscape to two 11x17" pages. Splice the pages and you have pretty much perfect USGS quad. I just came back from a hike in Wind Rivers and I had 14 USGS quads with me, covering all of the range.

Another option is this:

This site creates a seamless map out of the same USGS maps. You can print via PDF using correct scale and paper size. This is great for custom maps (although I still prefer quads as mentioned above).

To USGS: nice try, but until you add all layers present on real maps these are not any good.
