Re: [TenTec] Orion 2 situation

Thanks for the explanation, Cecil.  It makes sense.

Gulfport, MS eh?  Well it's been a lot of years.  I was in 
electronics/radar school at Keesler AFB from September, 1970 to May, 1971.
We were newlyweds then, and would drive over to Gulfport the back way to 
go to the Taco Bell, of all places.  How little we knew then!
More often than not, we'd stop at the mall on the way back to Biloxi.  
They had a KarmelKorn shop.
