Travelling light?

No cases or trolley bags for us, we have three fairly small (very small in Liam's case) rucksacks. But we have managed to pack them to capacity. Liam had the right idea, he kept saying 'but what if I want to buy stuff?'. Cliff's weighs 17.4kg and Elaine's is 19k. This is far too much. A clear out is on the cards very soon. We are even thinking of pulling out the pages of the travel guides we need rather than taking the whole books, not sure Elaine can bring herself to do this to a book though. Or photographing the pages we need. We are looking at the pile of books sitting next to our fridge (no, the one in our homestay, we didn't bring one along!) and we honestly saw fewer books on a bookstall in the Metro station today. We didn't pack many clothes or shoes, so we think it's the vitamins, first aid kit and books that are the problem. We'll post a packing list so that you can let us know what you think we should bin.
