We are gathering the rocks by hand from the woods and river beds behind our house, piling them in the back of the truck as we go, then driving them back to the retaining wall site for careful placement on the wall. Every time we complete a round of gathering/placing, we take a step back and realize just how long the process is going to take for a couple of amateurs like us. On the bright side we are really going to appreciate that wall when it's done!
↓ The wall is looking like this right now.
It will be imperfect and probably lopsided in a few places, but judging from how it's come along so far, I think it is going to look very cool when complete. Can't wait to share the finished pics!
