This list is a guideline for what you should plan to bring to Firefly. You don't have to bring everything on the list, and there are probably things not on the list that you want to bring.
We suggest that you label your belongings with your name / identifier or some other identifying system. If you will not be personally responsible for loading in and out any of your gear (i.e. if you will be putting it on a communal vehicle or someone else's vehicle), you should also label your belongings with “The Universe” in addition to your name/identifier.
Firefly also has a packing list on their website that you can refer to: http://fireflyartscollective.org/firefly/packing-list/
