The main gimmick of Country Road is the circular track and the map's changing entrances and exits. Because of this, the Dartling Guns, Mortars, and Spike Factories, aren't as effective, unless you can use them in multiples of four. Before placing your towers, think of the inside of the circle having nine main points. Center, Top, Bottom, Left, Right, and then the four diagonals. Place a Ninja Monkey first in the top left, and upgrade it to (3-2). You won't get (4-2) until later rounds. Once you get a (3-2) Ninja monkey, place a Monkey Apprentice on the north and south parts of the circle, Lead Bloons will spawn at the top on round 28, and the bottom at round 30, and then on the left and right, a few rounds later. Get the Monkey Apprentices to (2-2), get them to (2-3) later on. Keep placing
