Would love to see gravel/paved road surface info - whether it's a special layer or integrated into the map choice. This is valuable information for planning adventure rides.
A second piece of the puzzle would be public vs private land designation. More than once, I have planned a route with the planning tools and come to find myself faced with a gate, fence line or private property signage. Like the gravel/paved surface information, a public/private land layer would be quite helpful in planning adventureous rides.
