So, I drove through that block in Castle Hills this afternoon. The neighborhood is a nice 1960-70 neighborhood. Some of the houses are being replaced with McMansions. Some of the houses are more run down than others. I didn't see anything unusual. No big trucks or extra cars. i did see a dude out for a walk with a gun in his shorts; but, that's not too unusual here in Texas. None of the houses back up into warehouses or buildings - all residential. Close to Loop 410, our inner city loop. A house for rent. Looks like the Google maps images.
