Agree wholeheartedly. Here are just a few of the terrific westerns from that era:
The Virginian
Bonanza
Black Saddle
The Loner (created by Rod Serling)
The Rebel
Life and Legend of Wyatt Earp
Trackdown
Wanted Dead or Alive
The Rifleman
Tales of Wells Fargo
Rawhide
Wagon Train...
Man, it seems the Timeless releases have dropped to a trickle of previous years, maybe they have just mined most of what is available to them. I would still like to see them re-release seasons 3&4 of Laramie with better elements that they supposedly have found.
