I mentioned to a friend that I planned to line the perimeter of my dog run with cinder blocks. I hope this will help to keep the dogs in if they try to dig and it might deter the neighbor's dog for at least 5 minutes. If that doesn't work I might have to dig down, set them in concrete and chain the dog run to it.
Anyway, she mentioned that her husband had a bunch of blocks left over from a project. She forgot to ask him yesterday so she called him today and wouldn't you know it? He had just finished moving the blocks to the end of the street with a Free Blocks sign. She convinced him to retrieve them and I went over there after work and picked them up.
He gave me 14 blocks. I estimate that I need 25. This is great because there is no way that 25 blocks would have fit in my truck if I had to buy them at Lowe's. And since Lowe's is 35 minutes away, 2 trips would have taken a lot of time and gas. Now I have more than half of the block that I need for free, I only have to make one trip to Lowe's, and he has more space in his yard. Such a deal!
