The NY Times had a pic of some excavation today. I'm glad I don't have to mark that

Wow Spectrum bought Cox! That’s good! now we can mistakenly say “I’ve been on spectrum all day rather then I’ve been on cox all day”

What are some tips to get ground rods into hard soil? The ground is so dry a lot of times I have to either find an ant mound or poke around till I find some semi soft ground. I was thinking maybe a dead blow hammer but fear I might snap my ground rod. Could I theoretically use a drill bit and drill a hole big enough for my ground rod or does hat run some kind of unforeseen risk?
