"but I may have sources to search that are not available to others"
Ahh yes. The truth finally comes out.
At the convention, I cornered ewest and demanded to know about the sources.
He just replied "I have no recollection of that, Senator."
I could only reply "but I'm not a Senator."
When I queried him a second time, he again replied "I have no recollection of that, Senator."
That is when I knew that the identity of the sources would remain with the Master!
