I can see the benefit of sticks for walks, they can improve the aerobic value but a couple of those men resemble Labrador Retrievers that live near a lake or a wooded area, toting treasured sticks, logs and limbs around.
I'd say they are building a house... If they carry on taking bits like this they will be finished in 2024! So far they have a bit of the decking floor and some of the plumbing
They walked up that street empty handed all 3 times. I didn't bother including those videos here. I'm not sure why they would takes those items they found, just to throw them away. I suspect they wanted them for something.
