I've decided that I'm going to entertain some bids for demoing the remainder of the sidewalk.
However, rockhead that I am (pun intended), I've convinced myself to develop yet another alternative. (Yeah, you knew I was too stubborn for it to be that easy to just walk away, right?) Since a) this was the first of the blocks and b) it was semi-anchored to the porch and c) I now know what thickness is involved and d) it was also the biggest of the slabs, I might be able to get the remaining slabs up whole.
At any rate, my plan is to try to this week. (NOT tonight. I'm doing good today to move around though I'm not in as bad of shape as I'd feared. The sunburn actually hurts worse than my muscles!)
If it works, or almost works, great. There's my next step. If not, hand it over to some burly dudes.
