Absent a break injury, how far would JWB gotten?

Hi Juan. I don't have an answer to your question, but I'd like to add one of my own to what you asked. When Booth was at Garretts he apparently marked on a map his intended route --> from Port Royal to Norfolk, then to Charleston, then to Savannah, then to Galveston, and on to Mexico. Is there any other evidence that Booth was headed to Mexico, or is this route he drew at Garrett's the only indication we have to go on?
