Concrete cracking - Day Two - By prying up the entire slab & supporting with scraps, the slab would crack under impact vs. the force being absorbed by the ground underneath. The funny part was that the slabs were coming up in such large chunks that I had to sit on the prybar and scoot the scraps under with my legs! Yes, my neighbors were laughing at me, but hey, I got it done! ;)

Concrete cracking - Day Two - it took another 45 minutes to tackle the last section to the sidewalk since there were no existing cracks or seams! I could not lever out the entire slab, so making cracks took a LOT of sledgehammer hits before it would budge.
