RE:RE:RE:Today's NRKeno700. I'm assuming hole 21a is drill 1 and hole 22 is drill 2. I don't know why they would put the "a" in 21 unless the same rig was going to punch a "b" from the same collar so whatever drill drilled 21a is likely doing 21b right now. also, the may 27th NR contained holes 17b, 18a, 18b, 19a, 19b, 20a and 20b so I think all holes are accounted for.
btw, thank you MrBigger and ValueSpotter
