GDG- Meade and Lee's retreat from Gettysburg

[James Cameron]

<< Does anyone want to offer an opinion on a question that I have regarding 
Lee
and Meade and the retreat?  If Meade had access to a reserve of unused
troops such as McClellan had after Antietam, would Meade have been more
aggressive in following up and engaging Lee during the retreat?  >>

An excellent question, to which my  response would be that I don't know. 
I'm sure having substantial numbers of fresh troops on hand would have made 
some difference, but then again, this wouldn't necessary change the problems 
of weather, road conditions, supply, and Confederate defensive measures he 
had to contend with.
