Sean: here are a few courses that, while not worth a plane ride to see, are worth the drive if one were in the general area. You wouldn't be dissapointed...
-Devil's Paintbrush, Blackhawk, Muskoka Bay, Westmount, Beacon Hall, Brantford, Cataraqui, Coppinwood, Dakota Dunes, Eagles Nest, Lookout Point, Mount Bruno, Oviinbyrd, Redtail, Rocky Crest, Scarboro, St. Thomas, Shaughnessy
Based on other's opinions whom I respect,Tobiano, Royal Colwood, Victoria, and Humber Valley would be worth a drive as well.
Ronald: Most of the newer courses in Niagara don't really turn my crank. I like Whirlpool, but not enough to make the 90 min drive. I haven't played Lochness Links in a long time, but I keep hearing good things. In general, there is a lot of decent golf in Niagara, and some great deals.
Wayne: I'm not on the panel, although I'm pretty sure I've seen more courses, in more provinces, than many of the panellists. I agree with Ian that it would be beneficial for a panellist to have the context of having seen courses throughout Canada. The regionalism skews the results. As Ian rightly pointed out, I think without the regionalism we would actually see many more Ontario courses on the list. ie. Kawartha, Cherry Hill, Sarnia, Islington, Galt, Cutten, Beverly, Highland, etc.
