After winter is over in northern Europe, the cows can finally come out to play. Well, feed at least! To keep them from freezing, these cows are put up in a barn over the long winter. Now, they’re finally going to get to graze on green grass for the first time in months. It’s customary for the public to crowd around as the cows are released, and as soon as you see them jump for joy, you’ll understand why the audience comes back year after year for this unique spectacle.
