I will be traveling to Washington D.C. in a couple of weeks and need to travel light. I will be traveling by the Metro, so I do no want a large camera bag or backpack to encumber me. I will be taking one to two camera bodies, a wide angle telephoto, a long telephoto (i.e. 80-200), a flash unit, batteries, compact flash cards. My first day, I will be visiting the Capitol building and hopefully my senator. I will be wearing a suit. The following day, I will be in regular street clothes but will be working outdoors most of the day. I have a Domke photographer's vest, but do not know how many photo journalists actually wear these. I would like something that fits around the waist like a fanny pack that provides easy access to my gear. I also do not want to be a target for would-be thiefs! Any recommendations from the pros?
