The past couple Sasquatches I've spent entirely too much money on posters, seriously like $300+ a year. I was trying to avoid doing that this year since I have 20+ posters that don't even have frames yet. I think that's going to be a problem since several of these are awesome, especially the ones for Grimes, Sigur Ros, Youth Lagoon and Tame Impala.
Usually the artists don't even have the posters for sale (or even pictured) on their websites until after the festival, however in years past I've been in contact with some of the artists and they sent me posters before they were officially for sale. The only reason I bother with that is because some of them only have 50-100 copies printed and sell out very shortly after the festival.
Hopefully they don't decide to be anal about cameras this year. I have a zoom lens camera that I've brought in every day of the festival since 2010 and have never been hassled about it yet. Pretty sure that would kill my mood for a little bit if they refused to let me in with it this time.
