Conspirators' "Supplies" - Did They are Didn't They?!

[RJNorton]

Bob and Laurie, it has been speculated that David Herold may have ridden into the country on a scouting mission April 12/13. Possibly, during this mission, he informed Dr. Mudd of what was about to take place? We know that David spent the night of April 13 at Laurie's great grandfather's house, Joseph Eli Hunt, because he was caught in a rainstorm on his return to Washington. While staying at the Huntt home in T.B., he left behind a nightshirt bearing the laundry mark of John Surratt.

Is that the sum of the evidence that he may also have stopped at Dr. Mudd's, too? Or is there more evidence? I am curious about this scouting mission as it would seem, if true, Herold was on assignment to alert the Confederate underground "to be ready." Is it a real stretch to think he may have stopped at Dr. Mudd's?
