Your friend will have to purchase a barricade pass as a local resident for you to use. They are not free.
You will not be able to get into town without the barricade pass, so she would have to either send it to you or meet you outside of town to deliver it.
You will have to show some proof that you have the right to bypass the barricade in order to get into town, such as a Town Park camping pass or a Warner Field camping pass.
Simply telling them you have a friend in town will not suffice.
Good luck.
We're staying at 'Lulu city' condo for the fest this year. Will a printout of the reservation be evidence enough to get through the barricade this year?
