I don’t always take the backpack; this year’s Scotland trip was done with a carryon size, but I am now down to 1 carryon or backpack and 1 small backpack or purse. Some of it is because of a lot of work travel a few years ago and you learn real fast to pack light when you are stuck with luggage for hours at a time. The rest of it comes from more world travel where I’ve learned from experience that dragging a suitcase (even a small one) across cobblestone or uneven bricks is just not fun at all. I’m seriously considering the backpacks that are made specifically for travel and don’t have straps and are not top loading for wherever my next trip is. Anyway, it’s a funny memory and I’ve come a long way.
