Craig, to ATP!
Great find from your neighbor. I had a similar experience. My next door neighbor passed away and the crew fixing up the house to sell for the son (who inherited it), got rid of about 60 wall blocks by illegally throwing them into the vacant lot next door. They go for about $1.85 each at Home Depot. Unfortunately, they broke several of them by tossing them on top of each other. And we even approached them weeks beforehand and asked them about the blocks and they did not respond. When the supervisor of the crew came to inspect the work done, he was mortified to find all the blocks piled up in the lot next door. So he came knocking on our door to see if we were still interested in them. He didn't have to ask us twice. We pull our old van right up to the vacant lot and started loading the blocks into the back of the van. I managed to almost complete two small oval raised beds with all those blocks. Looks really nice!
Love freebies like that! You can see those raised beds in the article I wrote here on ATP. They are photos #10 & #11 in this article:
