Being the organized OCD person I am I made a bonnaroo checklist in Excel because I could not find another one. It may be useful for other people also so I decided to post it on here. Some things may not be relevant to you but you can edit it or change things if needed. It has the basics however.
MY OCD self has one as well! My excel file is about 8 spreadsheets deep including packing (what's in my roo pile, what I need to buy and what needs to be added last second), and 3 sheets dedicated to music. I have a list of all artists where I have listened to at least one youtube song for each and made comments about the type of music and how much I like them- I have fallen in love with some amazing artists this way. Also there are sheets with who I know that is going and ideas that I have found on inforoo (recipes and such). It's actually a google document which I have shared with friends so we all have our own columns to mark our opinions
