Have Toronto's bunkers changed much since inception?
Yes and no, the locations are mostly the same, but the bunkers are definately "cleaned up" from the origional look and style. Toronto is mostly intact.
I assume at one time Hamilton's and Toronto's bunkers were similar seeing as Colt built them within a couple of years.
Why aren't more courses like The Paintbrush and Osprey Heathlands built? It seems they offer really interesting golf on less than ideal terrain (particularly Osprey).
Glencairn, Red Tail, Dakota Dunes, Wolf Creek, Blackhawk, etc. I think there are plenty of similar courses
What is the architectural timeline of Rosedale? Seems as though more than a few have their imprint on it.
Course is laid out by Bendelow, renovated by Ross (13 greens), renovated by Robinson (primarily the first major change to 18, renovated by Cupp (current bunkering-6-12-2nd major rebuild of 18, renovated by Carrick Design, minor changes around greens mainly invoving shaving surrounds & rebuild of 18th once again.
