So, on other forums I frequent, this is a topic many find helpful (more helpful than item xxx will die and product yyy will vanquish them ALL!). Long story short, whats in your bag?
Start with a quick description of you and how you use your gear, then if possible post a pic of the bag sealed up, a pic of the contents with description, then a pic of it packed so everyone can get an idea of what others carry regularly and how.
I'll go first.
I come to photography from a long background, I used to help my sister shoot weddings, but never really got my own real camera. Various point and shoots etc. Last few years I've been doing lots of mini vacations with the kids and wanted to do a better job recording them than what I was able to on various cell phone cameras. This got me to start trying to cover all aspects of the trips, from the shots you often cannot get to the more standard and typical. I come from a background in IT, with backpacking as a major hobby so more with less and light and compact is a major theme of my gear, and theres really no fear of tech....
Below is my bag.

And the contents
