For what compares to that feeling of linearity - one point to the other, start and finish, via a straight line? When the interstate runs straight and dissappears over the horizon, wide expanses to either side, clear, clean, and the road traveled cut into that earth which it is layed on. Layed down as hot liquid concrete, solidifying -
