In October of 2011, MMM challenged his readers to use a bike trailer to get groceries.  This article gave a great personal experience from Mrs. Money Mustache, who for the first time biked to get groceries.  It was a great article that inspired me to try it out.  One problem: I don’t have a bike trailer.  So, I took the challenge by biking down the road with nothing but a book bag.  Here is my story of taking the MMM challenge in the spring of 2015.
