>>2452024Here's a piece of a map I made through more dialing-in of random campground in Michigan.
Lighter sat colors print better, and I hand-drew the public/private (pink) boundaries using a separate layer as a guide, then painted the structures bright red since that shows up easier than their default yellow. More work, but helpful in the field for sure.
This requires more effort than asking 4chan what to do, but get different layers from caltopo, copy-paste them to gimp/etc as layers, then alter opacity values and doodle to your heart's content. Then print.
