...and spend a day at Disneyland at any time in it's history prior to today, what day/period of time might you choose and why? Maybe it's the park opening, the arrival of several new attractions, but still some classic oldies that don't exist now, reliving a favorite time there, etc.
I'd have a tough time deciding, but I think I'd have to go with sometime in the first couple of months of DL's opening. I'd be fascinated to see the park in person in it's earliest days with many attractions that are no longer there. Maybe not the first day (crowds and gooey asphalt and all), but a very early day in the life of the park would be very interesting indeed.
