I'm not much of a traveler in most cases, but I've been fortunate to get around and see some interesting places, sometimes while on business trips.

I do carry a camera around a lot! My main camera is pretty compact and light, and I've gotten into the habit of carrying it anytime I'm walking around outside or even when I'm driving. I never know when I'll see something I like, and you can't come back the next day because the picture you wanted is often different then. Even though phone cameras are getting very good, they still don't provide the control and quality you can get with a good camera. I also dislike the processing most of them do in the background.
