I live very very close to MSP. I have noticed that there are semi trucks pulling cargo bins that belong to different airlines. To be honest, I have only noticed 2 that have an airline on the bin from a different country. I have seen a bin that has Maersk on it, and a lot that say Hapag-Lloyd. I have also noticed that they were driving pretty close to the premises of the airport. Anyone see these, or know what they are used for?
