At 500 miles, turn left.
The Gray Road is an area accessible from the streetlight in Red Streetlight World with four lamps on its left side.
The gray road is a looping area featuring a large network of roads with many intersections. There is a long railway bridge built across the center of this area, and it may rain or snow here periodically. There are numerous portals scattered throughout this area, which all lead to different areas of the dream world.
To the east of the entrance from Red Streetlight World there is small doorway below the railway bridge that leads to the Train Tracks, and just beyond it, a large basketball hoop which will take you to the French Street. Conversely, to the west of the entrance is a pair of metal barriers which will teleport you to Boogie Street if you walk in between them.
Back at the entrance, heading up under the railway bridge leads to an intersection with 2 crossings, and roads leading off in all directions.
A short distance to the west of the intersection between the road and the railway bridge there is a staircase which will take you to Grass World, and along the lower side of the road to the east of the intersection there is a small green plant that will take you to the Florist. If the weather is snowy, a traffic light near the intersection east of the green plant is visible, which will take you to the Techno Condominium.
Along the upper side of the east road there is a large colorful archway that will take you to GALAXY Town, and at the next small T-junction there is a grey streetlight just northwest of the corner, which will take you to the Dark Forest.
Heading up the road to the north of the intersection, there is a sideways T-junction that leads off to the right where there are two poles sticking out of the road. Walking between them (from either side) will teleport you to a small area that connects to the Highway. This is also the area you end up in after you've squashed all the houses in the Mini-Town in Toy World.
