Just thinking out loud here...I'm on the verge of ordering an Arkel trunk bag for my France trip...I was planning on using my small Axiom panniers and just use a shoulder strap when I'm off the bike, but they are still a big. I'll only be doing day trips on the bike, so I won't need something so big as my panniers. On the other hand, I already have the panniers, and the trip is already adding up. On the other hand (how many hands do I have?) the Arkel with a shoulder strap can be used just for walking around, too, on the days when I just want to walk around the Marais and cafe-hop. On the other hand, I have a just-fine-thank-you purse I could bring for those days...

I'll ponder it for 24 hours.
