During the 4th we were in upstate NY. There is a small town that you would never believe would house a Star Trek museum which includes Stage 9! An authentic reproduction of the Desilu sets used for the original series, including Engineering, Sick Bay and the Bridge, among others.

You walk into each room and can look at every detail,(HDTV or 4K not required) and take all the pictures you want. The guide gives some background and interesting tidbits about each area.

This is better than Must See TV for anyone who would have worn a Red Shirt just to be in the landing party, no matter how briefly.
