I will be going to NYC in a few weeks, and I'm trying to consider my best options for carrying essential gear (d7000,12-24, 50 1.8 maybe, tripod), while also avoiding looking to conspicuous. I'm well aware a tripod will negate that effort right away, but I would hate to need it and not have it. I am considering a slingshot 102, as that would fit the gear and also offers a spot for the tripod, but am also considering messenger bags in order to look less touristy. Any thoughts?
