i've been watching the Original series again i had to take a break from it for awhile because i had gotten burnt out by it. i'm still on season 2 now i'm up to " Back There' the Abe Lincoln time travel episode with Russell Johnson is in that one. the i think 2nd appearance he did for the show. a good one too that i just have not watched yet, last one i watched was "Dust' which i thought was boring for years but now i really like it.
