The vast majority of my available venue in my current life situation is event photography, which I enjoy immensely. My boys are younger and I'm a Scout leader so my time is limited where I can do photography and I combine my activities with my photography. I'm also in the process of setting up a home studio to do portraits as well. The D800 is great for most events that aren't sport-related, and my D700 is still getting use as the go-to camera for sports with its higher frame rate in continuous mode.
I'm going to take my D800 on next scout camping trip with my sons vice the D3100 for a change...am going to see if can wander off for an hour to try out some landscape and nature photography.
Photography is a great hobby/passion for any season of life.
