Who does tom joad go to 'lam' with?

I think he goes with Casey.

Whn Ruthie outs Tom as being on the lam, he's already left the family. He left alone, and he said that he would return when his face healed. Casy is already dead.

Ruthie says;

"An' Ruthie said, 'Oh, yeah? Well, our brother's a-hiding right now from killin' a fella, an' he can kill that big girl's brother too. An' then they called names an' Ruthie throwed a rock, an' that big girl chased her, an' I come home."

Hey I thought of that too Jill. I also considered that as soon as Tom left Oklahoma , he broke his parole which automatically put him on the lam. Then he meets up with Casey after he was arrested just before he is killed.

Good thinking, I didn't think of that. I guess in all reality he was on the lam with his family! :-D
