A rumor about a closed mountain path appeared on five travel websites. The different layouts made the reports seem independent, but each repeated the same photograph and the same unusual spelling mistake. A guide traced them to a single message posted after a storm two years earlier. The photograph was genuine; what it could establish about the path today was another matter. Instead of counting the reports, the guide contacted the staff responsible for maintaining the path and asked when it had last been inspected. Their dated inspection record indicated that repairs had been completed. The guide still advised visitors to check for new warnings before leaving. Repetition had made an old claim familiar, not current. Reliable advice depended on the relationship between a source, the question being asked, and the time at which its evidence was collected.
