Hi all, I am after some advice from people who have travelled OS with their camera gear if possible. I am heading over to the States next year and will be doing a couple of photographic tours, one for birds and one landscapes. My camera gear weighs around 10kg. In the past I have carried a backpack and no one has questioned it, but I find that I am getting older and carrying that much weight is a real strain! So I am looking at getting a roller bag, which will weigh a bit more than a backpack! I guess I am asking for information from others who have been to the US. How strict are they with cabin luggage weight? I really don't want to put expensive equipment in the checked luggage! Any information greatly appreciated!
