On March 7, the Rensselaer City School District will host the 2015 Region 4 Odyssey of the Mind Tournament. This year is set to be a record year for participation, with 108 teams from 36 school districts in Rensselaer, Columbia, and Greene counties registered to take part. Students from grades K-12 are put into divisions based on grade level, and are given a problem to solve on their own, without assistance from parents or teachers.
