It's always a tough decision what to pack in your bag for a road trip. Not too much, just the necessary things… but – what is the most important item?

That's what Challenge #3 is all about: the number one travel essential for a road trip. By posting their essential, people help raise a prize barometer. The more users post a comment, the higher the prize barometer will rise and the bigger the raffled prize will be. Participants also have the chance to win the main prize, a trip to Austria's Frequency Festival for them and their friends.
