The beginning of a semester can get costly. There’s the gas or the plane ticket it takes to get to campus. Sometimes there’s moving, which can mean lease application fees, security deposits, furnishing and more gas. Then there’s the cost of textbooks, school supplies, technology, granola bars, coffee and anything else that students need to get through the semester. These costs — and the immense barriers they can pose to some students — aren’t always talked about. Rice Mutual Aid, a student-organized mutual aid network, is trying to change that.
