This only details a minor occurrence in the area. If you'd like to see a more in-depth view of the location, check out Red County Truck Terminal.
In Red County, you'll find a large sign post saying "Truck Terminal Red County", with the word "Truck" and "Red" on top of each other on the left side. If there is any special place you could expect to find the special red truck mentioned on epsilonpogram.com, it might be here. Inside the terminal there is a strange blue glow, a phenomenon which can be witnessed at any time of the night during regular gameplay. The blue light is a unique occurrence in all and throughout San Andreas.
Strangely, the town of Blueberry is at the exact center of San Andreas map (0.0, 0.0, 0.0). This may or may not be a coincidence, but it is a strange nevertheless.
