Had some success this past weekend in Northern Ontario, where the focus was predominantly on mines, with a side helping of checking out the ruins of Gargantua Harbour in Superior Provincial Park. While Gargantua isn't going to make it onto the site, the two mines are. Both Ranwick and Tribag are available for viewing.
Needless to say, I'll be back in Northern Ontario in the future (hopefully). First, though, will come the third (and hopefully final) attempt to locate the Richardson Fission Mine; so far it has eluded me.
