I’ve been following & conversing with The Festival Lawyer on Twitter for a while now, and he’s always had solid advice concerning your legal rights at music festivals. I just now saw that he posted a graphical flowchart for what to do if you’re stopped at a music festival on Showbams.
Read through the comments as well there are some good clarifying questions and answers. Someone named Jen asks about the legalese on the back of a ticket and there are a couple of good replies, one from The Festival Lawyer.
Also read through his other articles on Showbams and … KNOW YOUR RIGHTS.
