Do you ever run outdoor locations (like, zoomed in regions keyed to a hex, rather than the hex crawl itself.)

What is your procedure for doing so? Usually I like marking off a bunch of points of interest that serve to funnel player character attention while paying attention to line of sight (not unlike how dungeon corridors and exits serve as an informational flowchart.)

Obviously I assume a larger scale rather than 10' per square and that since the location is dangerous, I am still rolling for random encounters.
