Could have done a car charge with key in the on position only. Looking for multiple options for charging. Solar seems to be good backup to the battery chargers we have. Son also 'broke out' an old iGo AA battery charger. It helped. We just bought more of the charging blocks (as we call them). I don't anticipate another flooding like what we saw. Seems to have been a combination of human error and clogged drains on the 'canals'. Thinking of a solar option though just in case there isn't any other way.

Other lessons learned will follow. More things happened.
