Thanks for the ping. I wondered about the 10-10 as well.
I was thinking the 10 - 10 was a date. The first one is a date, pretty obviously. 10-10 as a date in October, 10/10 would perhaps mean what ever is going to happen would happen between those two dates as well> Or another 9-11 on 10-10. Or transmission over with CB lingo, or whatever else you want it to mean.
