Where was Lot during the famine?
In Lech L'cha there is a famine so severe that Avram has to leave Canaan and go down to Egypt for food. He leaves Egypt with great wealth, and then in Bereishit 13:1 he continues traveling with Lot. Lot isn't mentioned in the Egypt part of the episode.
Did Lot go to Egypt too? If not, how did he survive the famine -- how was he able to stay in Canaan if even Avram couldn't?
We know that after the famine Lot had significant flocks and herds, enough that he and Avram had to separate (Bereishit 13:5). The text doesn't tell us when he gained those, though, so I don't know if pre-famine he was richer than Avram, could survive in Canaan on his holding, and didn't share.
