The t-shirts traveled through three forms of transportation: shipping by sea, truck transportation, and rail transportation. They were initially shipped from Colombia and Bangladesh to Miami by sea, then transported by truck to a train, which carried them further inland. This multi-modal transportation system facilitated the efficient movement of goods over long distances at relatively low costs.

The t-shirts went on a journey through three different ways of getting around: first they sailed on a big ship from Colombia and Bangladesh to Miami, then they hopped on a truck to keep going, and finally they rode on a train to go even further. This cool system of moving stuff around helped the t-shirts travel long distances without costing too much money.
