If I'm not mistaken, Colt's 1911 visit to N. America was princiaplly made to0 layout Toronto GC. This is, perhaps, when he also visited CC of Detroit. Although, I'm not sure.
Coincidentally, his 1913 was instigated by another Canadian commission at Ancaster, Ontario, to design a new course for Hamilton G&CC, where the Canadian Open was played last week.
I know for sure that Colt left Ancaster for Pine Valley. His individual hole drawings for the Hamilton G&CC course, which hang in the clubhouse today, are eerily similar to those in his 'Pine Valley booklet'.
