Railroad Family Exploring
It was probably very early in the public history of McDonald Observatory when the Jim Baker family made their first visit. With 3 preschoolers (Warren, Mildred, and Roger), it must have been a Sunday near 75 years ago, probably when Jim was operating a Burro half-circle crane for the redecking of Southern Pacific Railroad's Pecos High Bridge.
A white placcard on the door, and the man peering through the glass would indicate the observatory was not open to visitors. We did pet whitetail deer in the yard.
