I had a trip to 5040 on Sept 2, 2017. One of the purpose of this trip is to test smart phone as GPS for backcountry trips. I relied on Gaia App on an iPhone 7plus for two whole days. About 5040  Cobalt lake was unbelievable. Comparing to the summit, I enjoyed the lake more. The temperature was probably between 20 to 30+ for the three days. We didn't use our tent fly. Air was dry. Washed a shirt. It's dry over night. About Gaia I have only seen my friends using GPS handhold devices. I have waited for better options for years. I have always hoped that my smart phone can do the same. I finally decided to test this idea. I have relied on my iPhone 7plus as GPS on this trip, I think Gaia on an iPhone meets my need of a GPS. My two concerns were, battery life, and robustness. To save the battery, I turn the airplane mode on, also the phone has power saving mode. Which turned off some background process according to the help message below that setting. During this trip, I

I started practising archery since Feb 2017. My three finger release was unclear. So I started to read about thumb releases. After comparing the common thumb ring and manchu thumb ring, manchu thumb ring is more interesting to me. - Cylindrical thumb ring is not interfering with hand function as much as the Mughal thumb ring. - Can be wear on both hands as the same time. I am training to shoot with both hands. - May have somewhat cleaning release than Mughal thumb ring. - Works as two rings: for warm and cold weather. Thumb size changes when temperature changes. Since the ring is not exact circle. It's more ellipse. When the thumb is thicker, it works as "A" shown in the drawing below. When temperature is low, and the thumb is thinner, I turn the ring to "B" position. It still grip well. Here is what I learned in a few weeks. Resources: - How to use a Manchu ring . - This youtube Size: - The hight of the thumb ring, it works the best if it matche

Writing is a better way for collecting my thoughts. I hope this doesn't sounds like preaching. Life is full of challenges. It's a waste that everyone has to start with a blank sheet. Each generation have to learn the same lessons, make the same mistakes. What life taught me can't be passed to you easily. Not only they can't be passed on, it's also so much to pass on from one generation to the next. On the other hand, life would be boring if you knew everything from birth. Maybe mistakes have to be made so that we are not bored to death.  Everyone walks ones own path, experiences what one needs to experience. No one is able to take your place. When you need help, I bet you that you will always find them. I have found mine when I needed them, from books, videos, and people.  I am hoping that this post is one of those helps, and a place we can all revisit. Here are a few things worth mentioning. You may already know.  What matters?   Only a f
