Rob,
I live in Winnipeg (pop. 700,000), which, back in the golden age was a thriving city, a hub for east-west transportation of goods. That wealth brought the very best architects to the city to build courses. Donald Ross designed Pine Ridge & Elmhurst on the best land northeast of the city, and 9 holes at St. Charles. Stanley Thompson was responsible for Glendale & Niakwa, while Alister Mackenzie designed 9 holes at St. Charles. Willie Park Jr. was also active, designing both Southwood & Winnipeg golf club, the former, soon to be NLE.
Once the Panama Canal was built, shipments across the continent didn't go by land, and the city lost its momentum, and golf course architecture stagnated.
