I used a 18"x1/4" drill bit from homedepot not a concrete but just a regular bit then I use driveway markers they are 4' long rods. I read it on a thread some were. The first time I also used a big concrete bit and it didn't go so well. The 1/4" worked great
I can see 1/4" being easier to work with, what kind of rock did you drill through and what are driveway markers made of? Thanks- 4 the info
