In my free time, I enjoy making things with rocks, doing patio jigsaw patterns in quartzite around my house (I have one patio where three stones that made an excellent map of California are in the middle of the patio, and have rays of rock extending out from it; and another that is a kind of rock whirlpool around a Japanese maple); I also am stacking and re-stacking a drywall lake front at my wife’s family place in Maine, made of glacial cobble so that every winter the bad work I do slumps back into the lake, while the good work holds longer.All this rock work, I realized, is like doing novels that I can actually see, which is why they give me such pleasure. My conclusion is that everyone should make things for the fun of it.
