grambo,

Thanks so much. Do you know where I can find out more info on tours, where they were at certain times, etc. I am trying to find as much info as possible.


Thanks again,

Jason

The unit should have a command chronology which lists where/when/what the unit was doing. It also often lists large events by name of the individual. I can't guarantee that they'd be very interested in looking back that far, but they may be willing to help.

no shame

Sorry JKING, I have no idea.
