Horse trading was lively this night. In addition to the English wheel finding
a new home with Chris Daniel, a hand tapper that John McCalla had brought
followed Dave Welser home.
The meeting continued with general discussion until we had dwindled to a handful and then ended about 11:30 PM. The night owls once again headed out for late night eats.
