Sounds like ya did just fine. I think as long as your prepared with water, food, and gps have at it. I go occasionally for days without service. I give my wife a 10 digit grid and tell her to call it in if I don't contact her by a given date. I'd probably get a sat phone if I was going longer then 96 hours. I was stalked within 10 feet by a big cougar alone one evening (pistol was in the tent...). I now always have a side arm on 24/7.
