First and foremost, welcome back spring breakers! Speaking of spring; now that the weather is finally beginning to show signs of warm sunshine and rain instead of snow, let's talk about summer.

We all know the most fun apart about summer, besides the fact that we are once again out of school, is going to music festivals and pretending to be a hippy in the '60s and '70s for a few days. Let's face it; music festivals are the highlight to most people's summer vacation. Well this year, I have made up a list of the top seven music festivals (that aren't yet sold out, and only in America, mind you) I think you should save your money for this summer break.

And the line-up for June-August is:

Bonnaroo (Tennessee)
June 13–16

The Bonnaroo Music and Arts Festival happens every year and lasts for four days. It is created and produced by Superfly Presents and AC Entertainment, and is held at the Great Stage Park on a 700-acre farm in Manchester, Tenn. The main attraction for the festival is the multiple stages of live music, featuring diverse musical styles. However, the festival began with a primary focus on jam bands and folk rock.
