They went on a 7 1/2 mile trail. We (her mom and I) waited awhile and then went to see if we could borrow flashlights to shine so they could see the way back. They showed up about the time the ranger did. He was concerned that there was an older couple still out, way behind them. Her mom and I were worried about bears and mountain lions but they were just having a good "ole time". My 31 y/o son laughed when I told him he wasn't at Disney Land. He's a good survivor but when it comes to navigation... He has lot's of stories of when he was a medic in the Army about how he would got lost and would show up hrs or a day later:').
If I went on a seven mile trail, it would be on horseback. : )
