That sounds like you may have learned the same way I learned that 1: when a USGS topo map indicates an unimproved road, it may be out of date, 2: don't take your father's four-wheel-drive truck down a late-winter, corn-snow-covered dirt road when the temperature is starting to drop in the late afternoon 3: Don't go down a dirt road on a hill covered in corn snow without walking the path first to make sure you can get out or get back up. 4: When looking for a winter campsite for your Boy Scout troop, tell your parents where you're going.
