How to Prepare for the Epilogue - RDR2

After the Chapter 6 mission My Last Boy, you'll do all the things you want to do before the Epilogue and BEFORE starting the mission Our Best Selves you'll want to prepare for the epilogue including sending all your money to the Epilogue. This is when you do the Aberdeen Pig Farm Encounter for the first time. If you already did this earlier in the game, you won't be able to send the money from Chapters 1-6 to the Epilogue
