The small bag is a problem. I have a little bike bag this trip (only about 6/7 litre storage capacity) but since I now have a separate camera bag, it’s worked quite well.

and most definitely, I wish my current bag only had this amount of gear in it
The one thing I’ve thrown in a few times for novelty is some tiny trinkets/souvenirs from Ireland – a tradition we picked up in Israel for giving to locals – even just some postcards showing photos from home. It’s an easy way to show where you’re from and expand people’s ideas of the world (as mentioned in your other blog post)
