I may be heading out on a road trip soon. It will involve some backpacking so I am looking to go light. I figure a good way to do this would be to send some of my film in for developing while on the road. I HATE the idea of hauling all my exposed film around with me or having to leave it in a car. Plus, I like to break up large batches "just in case". Now I have never used one of the large national labs. I need a recommendation. I mostly shoot black and white 120.
