I've seen here in Houston a pretty good number of homes built in the 50's and early 60's that had open bbq pits made from brick. Some were no doubt built by the homeowner, but I think also the builder would offer these up as an option, like it was a trendy thing there for a while. Some of these pits still stand as built, but most are pretty much rubble at this point.
Relics from another time.
The Line-up: 22.5 Weber OTS; 22.5 Weber WSM.
Gone but not forgotten: ECB (modded); New Braunfels Hondo stick burner.
