I desperately need that demolition hammer (or electric breaker)! We recently purchased a 1957 ranch in San Fernando Valley, CA, which includes a completely-paved-over backyard AND a vintage diving board. We removed the board since the bolts were completely rusted and it's unsafe, but the cement supports remain and need to be removed.
Secondly, we have a few fruit trees that are suffering because the pavement comes too close to their trunks, inhibiting their growth and ability to get water and nutrients. I'd love to remove a large area of the cement and put in some paving stones and a nice vegetable garden. It'd also significantly help with drainage in the rainy season!
