Where Was George Washington on May 5, 1783?

Nancy Hanks was conceived around 5/5/1783. I am searching for Washington's noted whereabouts near this date. It is proving quite difficult. It appears to be a mystery. Why? Was he in Hampshire County? On what business did he meet up with the young Lucy Hanks? Was he bathing in the "medicine waters" at Capon Springs?

On April 19, 1783, Washington announced to his army that England had agreed to a cessation of hostilities with the United States. Eight years, to the day, had passed since Massachusetts' militia traded musket fire with Redcoats at Lexington Green. By the end of the year, the last English troops had shipped out of New York, and Washington came home to Mount Vernon on Christmas Eve.

Did it take GW 8 months to go back home to Mount Vernon? Surely he must have made a few stops along the way?
