The note can be found inside the Nuka-Cola plant, on the body of Winger Mercier upstairs in the office section, near the shipping section. The note points you toward an optional objective of The Nuka-Cola Challenge.
The Formula for Clear Nuka-Cola is on the first floor of their D.C. Plant. That's where they did all the R&D for it. Get the formula and meet us at the Red Rocket Tricycle Factory as we planned. Our buyer is promising lots of caps, so I want to see some hustle! This could take our gang to the big time. Sudden-Death Overtime forever.
- The note mistakenly refers to the Red Racer factory as the "Red Rocket Factory", whereas Red Rocket is an automobile service company.
