We had a bear on our site too when we were there on the Canada Day weekend. Our tent neighbours had food out - so the bear was there and then got curious and came to see if we had anything... luckily we were all bear-proofed but still an interesting experience!
I usually leave my BBQ out but not at Grundy Lake. I have dog food out during the day but the bear wasn't interested in the dog food. I had raccoons at Silent Lake stealing the dog food.
Thanks for the informative site tour, I had a site reserved but I changed it to one of the ones you showed in the video because it looks much better and I also was able to reserve that lovely site 305 for 1 night 👍
