On Mother's Day, we decided to pull up all of the tiles in our side yard. This has been plaguing us since we moved in, but finally decided to tackle it. In the process, we found that the previous owner installed the tiles over existing sidewalk! Bonus, since that's what we were planning on doing!
The aftermath of all of the tiles being pulled up:
114 full tiles, 9 half tiles, and 6 tiles with cutouts for fence posts and such. 18" square. That was quite the workout...
