I am impressed with your accomplishment and admire your wife's support to your adventure. Is this part of the route for bus to travel from Taipei to Yilan in pre1960 years? The side walk is also very well paved and it is great to see trains running fast along the mountain slopes. I walked from Gongsan to Tainan or Kaushung when I was in ROTC. I could feel your strength and will to complete this nice video for us! Thank you very much! Take a break to enjoy life with your wife!
