I always leave a detailed hiking itinerary with my sister before every hike but I'm not sure what to tell her about when to call authorities if I am overdue. What do others think is the appropriate amount of time to wait before reporting an overdue hiker - On a day trip? On a multi-day trip? Would it be different for a solo hiker vs. 2 or more. Not sure it matters but I do carry a SPOT but would only use that in an extreme emergency.
Thanks.
