ProposalProgress continues, with occasional setbacks but lots of successes.
A lot is getting
done.We are now on a day-by-day schedule...
the change in DAQ procedure; we start in the counting house conference room since we aren't allowed to turn stuff on in the tunnel until the ORR. We are actually bending the rules a bit by turning on stuff in the counting house.
