[1] The Baltimore and Ohio Railroad’s mission was in part to connect the Chesapeake Bay with the Great Lakes. Lake Eire here was the obvious place.

[4} In three seasons, 1959, 1964, and 1968, each team had big wins against the other. The Cleveland wins in the regular season at Baltimore in 1959 and and 1968 are in my opinion the biggest the Browns ever had.
