Mississippi , I believe is closed in the lower reaches due to flooding.
Take a look at a map, Rounding Gaspe will put you at a latitude slightly higher than
Lake Superior. If you leave November 1, in that

If the Champlain locks and the Troy lock open as they are supposed to in the next 10 days, you could
head south from Sorel in
Quebec but you would have to unstep your
mast for the low bridges, that would get you into the
Hudson River. Maybe by that time The USCG will have lifted the Hazardous
Navigation warnings for the
Hudson.
