Relentless Boardmasters Festival this year should be amazing! There's extreme sports; skating, bmx, and of course surfing, lovely loud music with The Streets, Calvin Harris, The Super Furry Animals and a load more, and importantly: surfing competitions.

V the volunteering charity is taking a big purple bus (a strange looking thing with an umbrella) around the country and hitting the summer festivals. It's going to Boardmasters, and offering free entry with it. If you give up 4 hours of your time to help them with photography, or putting up umbrellas then they'll give you more than a "feel good" feeling - they'll let you in for free.
"The vINSPIRED Bus is currently touring the UK looking for fun and energetic volunteers to join the bigVbus team. We’re on the look out for volunteers who can give us just 4 hours a day helping out with photography or putting up umbrellas at the Festival. The volunteers will get to enjoy the rest of the festival for free as a thank you for their time. Go to http://bigvbus.vinspired.com to sign up as, or for more information about the opportunities available. "
