This is a continuation of the The Rainbow Trail at Liberty Reservoir - a simple, kid friendly, dog friendly trail through the woods around Liberty.
Some colors aren't in the rainbow, but they still deserve their own cache.
Grey or gray is an intermediate color between black and white. It is a neutral color or achromatic color, meaning literally that it is a color "without color", because it can be composed of black and white.
Gray is the color of a cloud-covered sky, koalas, wolves, ash, lead and iron.
If you follow along the trail and visit the non-rainbow colors, the trail will loop back to parking.
Parking coordinates have been added. Just don't park right in front of the gate and you should be fine.
