The recent addition of the Bethesda got me thinking that having some aerial views would be nice. Well, luckily there are some online resources for this. Here’s a link to Microsoft Terraserver showing an aerial photo ca. 1988. I know that much of the RR was wiped out by then, but it’s a start to gain some perspective on the city since online resources are so scarse.
