The Astrodome has been in the news lately, at least The Houston Chronicle, so I've seen several historic photos of that well-known structure. The aerial below was one of the best. It appeared on the Traces of Texas Web site. You get a good view of how things looked around Reliant Stadium back in the mid 1960s.
Kirby Drive is in the lower left. Old Colt Stadium is in the middle left. The Medical Center (along Main and Fannin Streets) is further in the background on the left. If your eyesight is good, you can see the Warwick Hotel (now Hotel Zaza) further down Main St. towards the middle. Downtown Houston is on the horizon beyond it.
I think the large white complex in the middle distance behind the Dome at roughly 1 o'clock is the old Veterans Hospital on Holcombe Blvd.
My classmate, Marsha Bauman Shaw (DHS '68) took the next two photos of trail riders as they rode near her home in Memorial in February. Of course, they were on their way to camp at Memorial Park. I found some photos of Salt Grass Trail riders camping in Sugar Land in 1954. I'll post them next week.
