I carry a lowepro Orion AW hip/convertible to backpack case in the trunk/boot of my car at all times. It has a Hasselblad 201f, 50mm, 80mm, 90mm Great Wall lens, 150mm. and the dedicated hood for each Zeiss lens. Either a zero 6x9 pinhole camera, OR my vivitar slr with helios lens, a Gossen Lunasix 3S, Cokin filter holders (wideangle, and standard -pro kits) and associated bay 60 or 70 mounts. 10 rolls of film in the lower half and 10 stored in the removable top portion along with my filters. It's a lot in a small compact package, and ready to go at a moments notice. The top and bottom seperate and allows you to scale down even more if you need to. I find this works well for carry on in airplanes. Tripod and cameras overhead while film and lighter pieces in the removable top under the seat in front.
My small SUV (Rav4 Sport) has a small compartment in the rear that allows the camera bag, tripod, and monopod to be stored out of view. Very handy, and in summer it does not get warm like the rest of the interior does!!
In the glove compartment of my car is a Minox 35GT loaded with 100 speed Legacy-Pro film, an Olmpus XA loaded with Kodak 400 CN, and a Yashica T4 with color print film. Overkill??? Maybe.
However, there is never any excuse to not have a camera with me. When I park the car for work, I'll either take the XA, or Minox with me in my laptop bag while I walk from the parking lot to my office. If I didn't have a camera with me, that would be when I needed it! I've had the opportunity to use all of the compacts in my travels.
Then I have the blad and the more serious tools at my beck and call when I want them. I've been known to see something that grabs my eye, go back to the car to get my blad and take the shots I want then go about my business.
I'm a photo addict and am not ashamed
