Claims in Mauritania
I'm about to start traveling by moto through Mali, Mauritania and Morocco. One part of border crossings that I am unfamiliar with is "claims". I have read that you must claim all of your money (and equipment?) at the border. I am unsure of why we are doing this, and when doing so, do we claim all money that we have (for example, the travelers checks stuffed and taped up under the moto seat). Also, if I'm claiming a few extra US bills that I have in my bag, are these border gaurds going to be enticed to start laying out fines because my shoelace is untied and take my cash?
Thank you in advance for any information on this subject.
