I don't have that kid of time, especially since I have already spent too much time on this thread (and FR as a whole) today! LOL!
Hijack alert: btw, we have had tons of rain around here lately, we have perfect conditions for sink holes to start above the areas that have been mined.
I have been shoveling snow since 3 AM. It is now 11:30 AM. I drop by this desk now and then to get a drink of water and a bit of psychological abuse and then it's back to the shovel.
