Everyone has their preferences for equipment, how they carry it and their style of shooting.  As time went on and I experimented with different styles more, I started picking up more and more gear.  I had to figure out how to carry everything from when I'm rolling through TSA in San Francisco International Airport or lugging lenses and supplies in a rucksack through miles of swampy bog in the Irish countryside. In the military, teams and equipment are deemed mission capable when they are ready to perform any operation within their scope. Wherever your missions take you, you should be able to depend on your gear to help you achieve your objectives and get you home safely.  You will often find that cheaply-made equipment simply will not rise to the occasion when you need it the most. Below are some of my all-around favorites. I've also linked them so you can check out the exact specs, price, and details.  

I've been on a serious search for a calendar that I can actually use for a better part of the last ten years.

I've tried paper organizers, post-it notes, writing on my arm, and so many mobile apps.  Yet, no matter what I do; I can't seem to settle on one.  This begs the question:  What makes a good Calendar?
