#28 Pass To The Underground
At my university, a parking pass was $200 a month. You needed to use the parking pass to gain access to the underground lot, which was heated. Long story short, we figured out the parking passes had a magnetic strip on the back that was useless because the machines would read the barcodes at the top.
Six of my friends bought parking passes, photocopied them and glued the barcodes over the tops of older membership cards. It ended up costing us just $30 a month. It was the best year of my life. We live in Canada, so underground heated parking in the winter was the dream.
