I almost always carry my camera in a camera only bag over my shoulder. I often end up carrying the camera most of the day but at least I have a place to put if I need to quickly. I do not use a strap on the camera itself except for special situations such as the heli photo charter.
I place the rest of the gear in a backpack. This includes misc camera gear, a GoPro with accessories, a monopole and a tripod. My wife usually wears the backpack so I can take items out without having to take it of.
The backpack has a lot of smaller compartments and one larger. I looked a camera specific packs but have yet to find one that suites my needs. I'll just have to keep looking.
I'm also eyeing a full height travel tripod as my current one is just a little to long to fit in the backpack when collapsed.
