Filtering Events with "Categories"

We can keep multiple types of events on a unified calendar, and display the ones we want by adding Categories to each event. For example, I set up a demo calendar with a bunch of fictional entires using two categories. One is "Third Party", and the other is "Veteran Activity". 

We can add a "block" of events to any page on the site, and we can choose which events appear in that block, filtering by category. So on the right of this text, there's a block of events that use the "Third Party" category. Beneath this text, below the line, there's a block using the "Veteran Activity" category. 

You can create as many cateogries as you'd like, and there are multiple ways to display a block of events (for example, you don't always need to use the photos).
