When I was working production, many times the location on the call sheet would be kind of vague, particularly if we were shooting somewhere remote where there were no obvious house and street numbers, or deep within a park, forest, or open desert. But since I have retired, one of my pastimes has been off-roading in my Jeep. In fact, I am the president of Desert Wranglers Jeep Club (www.desertwranglers.club) based out of the Las Vegas area.
One of the first things that I learned was to always use GPS coordinates to identify a given location or meetup spot. That took the guesswork out of searching for (non-existent) street addresses when there is nothing around but dirt roads and lots of nature! Your smartphone and car navi system will show you GPS coordinates (hit the COMPASS app on your phone), and if you punch those coordinates into your navi or map search -- it will guide you within several feet, even if there is no official path or road.
