Always. Today it was a Mamiya 645 w/ grip, a 150 f3.5 and an 80 f2.8, some screw-on close-up lenses, a Luna Pro F meter, a Nikon SB-28 flash and an Ikoflex la TLR. Various filters for each camera and a few other accessories. Large (heavy) bag to hold it all and a Bogen tripod in the car. Also always have my Canon G10 with me if I feel lazy.
