You have an indomitable spirit to have travelled so far for only a day's outing. I'm quite certain that any of the Group of Seven would never endeavour to undertake such travail. I used to think that it was a little crazy to drive for three hours to visit a cottage, either one's own, or as an invited guest, for only what's left of a Saturday and half of the following Sunday before having to make the return journey, often in horrendous traffic. I could understand making the trip for an extended stay of a week, or more, because by then there would be ample time to drink it all in.
I suppose that I was lucky in that camping trips and invites to a cottage were regular occurrences when I was young and I didn't need to concern myself with the logistics and the driving. Eventually, the family (parents) had their own cottage in Muskoka, built from the ground up, secured to an igneous outcropping as foundation. It took seven years of weekend trips to complete the task, only then to be sold shortly thereafter to a wealth corporate executive that probably tripled its size, although I don't really know because I never went up there again. I was no longer a kid by then.
I've visited a few campgrounds in Provincial Parks in my time, although nothing comparable to your explorations, and found them appealing enough early in the spring, before the mosquitoes and the black flies, and the crowds. Killbear is such an enormous establishment, with so many camp-grounds as to rival the summertime population of a small town and that quality doesn't really appeal to me. BTW, that shiny texture on the rocks surface was very likely caused by tiny mica flakes, a metamorphic manifestation called schistosity. Fitting, as it were, next to campocity. I like to make-up new words. Never let me write a script for one of your videos cuz I'll make a hash of it.
