I agree that Don and John are great posters and wouldn't want eithe rof htem to ever stop.... until they are retired on the beach in the sunny south with the riches from DE/WF et al.
If I have one slight favorite, it has to be Don.... I too am a TML fan, have been since in diapers and will never change to flavour of the day. So he has my vote. Therefore if I sound grumpy at times I have a right and a reason.
Back ON topic for a bit, I think they struck something unexpected while doing the geo and hydro drilling for the ramp. What that is can only be guessed at, but it is significant ...ergo the halt.
JMHO
