I've been accumulating gear at a frightening pace, and I really haven't figured out a good way to carry it all conveniently.
Life was simple when all I had was the 10D body and the 28-135 zoom. My garden-variety camera bag served very adequately. Then, I started picking up more and more lenses and accessories, and suddenly I now have in addition to the original camera bag, two Halliburton cases, a tripod, and another canvas bag.
I'd be interested in hearing how some of you---particularly those who also have a lot of equipment---handle it all when you leave the house. I'm fortunate in one respect: I have a pickup truck, so I have no concerns about getting everything from Point A to Point B, but it's pretty overwhelming once I get to my destination.
Also, do you let bellmen handle your equipment in hotels? I don't, and this greatly complicates the process of checking in at hotels.
This is a problem entirely of my own making, but I know some of you must have come up with elegant solutions. Thanks in advance for your helpful suggestions.
