Where do they go in the winter?

 I stopped my walk yesterday to hear the approach of geese.  These Canada geese were honking as they went.

 They must have just formed up into a line, because they weren't an organized "V" yet.

And standing alone near me was this guy, who definitely heard them going by also.  But made no effort to join in.

The question I've been asking, Where do the go in the winter?  Down south is everywhere from South Carolina, to Georgia, to Florida.  I imagine there are lots of wetlands.  I just haven't ever heard of the main area they might like.
