When I was just a little boy the PD3751's Silversides were new in the Greyhound Fleet (1947) and I use to go on trips with my dad who was a Greyhound bus driver from Miami to Key West,FL and back.
I have always thought the Silverside was one of the best GMC Coaches that GMC has ever built.
Later the PD4104's and the PD-4501's Scenicruisers were in the fleet and the old Silversides were 2nd section coaches.
I hated to see the old Silversides leave the Greyhound fleet.
Now I look back and see how much the bus industry has changed since the Silversides were new it's sort of scary.
But that's progress you see.
Thanks for the memories.
