I found this in my box of old stuff. I remember picking it up off the sidewalk after a march in DC when I was a kid, back when I'd spend weekends roaming the Smithsonian or the back halls of Capitol Hill.
Yeah, you could do that then. No one to say "Hey, kid, you're not allowed back here." We were allowed everywhere, even places we weren't allowed weren't all that heavily guarded.
It's hard to believe the ERA set off such a firestorm. The primary complaint at the time, as I recall, seemed to be about sharing bathrooms.
I guess men wouldn't want that, given the line at so many women's public toilets.
