For those who have the opportunity to be in this part of the world in July, this is a highly recommended and awesome event. Of course, for the young, energetic and big party goers.

I have been there two years (2002-2003), it has grown since and has gotten a bit commercialized (MTV and such), but it's among the best festival parties I have ever attended (and I have been to quiet a few). Skip Ibiza, and go to this thing it rocks. The level of energy is simply amazing.

You can do a search on Youtube, see some amature videos to get a glimpse of what its like.
