When I was 9 and 10 years old my Father (in the Army) took me up Mt. Fuji.
Fast forward 40yrs. My son and I, not being able to go to Japan, decide to try to summit Mt. Whitney. After training for 6 months and buying lots of gear(56 pounds in my pack) we summitted on our first try in 2002. We have summitted every year since, 5 years now. My pack for 3 days now, with food and water, weighs 36 pounds. At 56yrs young I'm hooked on backpacking and will go on a 50 mile hike to Mt. Whitney next year. Then the High Sierra Trail, then The John Muir Trail, then the PCT thru hike!!!
