I have to admit, I admire you for what you did. Three hours and fifty minutes, four miles of walking in the water on and between slippery rocks to reach your destination, which is a pool, it's pretty amazing.
It's been a while since I did something similar but I still remember the feeling and the trouble one has to go through if it chooses to do that.
However, the result is amazing, looks like you had a lot of fun and that's what it matters ant the end.
I would have loved to see your way back in the dark. I bet that's not as much fun.
As about bears, I live in Romania where there are many, danger to the population and livestock. Bears are protected and no one wants them. The government made a proposal to the European Union hoping to redistribute some but no one wanted them, not even for free. Good thing you didn't meet any on your way.
Anyway, nice journey and video as well, looking forward to your next one. Till then, stay safe.
