My fiancee and i were enjoying the night out on the boat at our camp in mansfield, quebec near " bryson lake lodge outfitters". we had no light on the boat, it was a beautiful opened clear sky. so we're just sitting in the boat and talking and looking at the stars. when we noticed an object in the sky moving arround in ways that an airplane wouldn't be able to move. we lost sight of it and made nothing of it when suddenly we noticed something above the trees across the lake. it was square shaped. had a big bright light on top wich made it hard to see the shape. it was hovering arround like it was searching for something and i guess it couldn't see us on the lake. we observed it for a good 30 minutes until i descided to take my flashlight and make signals at it. shortly after that, it dimed it's light and disappeared. it also came back the next night at the same time. we observed it doing the same thing then it flew back in the sky till we lost sight .
