"One Rotary tradition is that students cover their blazers in pins and patches they have traded with other students or bought in places they have visited as evidence of their exchange. It is popular for the students to bring a large collection of national- or regional-themed pins and trade them with students from other areas. This tradition is popular worldwide." -http://en.wikipedia.org/wiki/Rotary_Youth_Exchange
