E-World / 이월드: Boomerang – What might be very conventional for us Westerners, seems less so for Asians here. E-World has a Vekoma Boomerang with the old Vekoma trains. The track is barely visible as the trees have grown through the structure, giving it a special integration. Despite its age, it's one of the best Boomerangs I've ever ridden! It's very smooth and comfortable, so you can enjoy the ride forwards and backwards with a pleasure that had been lost on other models around the world.
