"Stump the Yankee"

[Laurie Verge]

I'm not dead on this one yet, but it is frustrating me. I can only put McCullough in D.C. between March 11 and 26 in order to put your incident within three weeks of the assassination. What I'm hitting is Booth taking McCullough (who didn't ride horses very well) for a ride and pointing out escape routes along the Eastern Branch. That doesn't seem too beserk, however.

Bill Richter, here I come for guidance...
