It's a shame because I moved to Cincinnati Ohio two months ago and I haven't seen a busty woman yet. I lived in Camden NJ which is across the river from Philly and I took it for granted that I would see a massively busted woman at least once a day.
The bustiest candid sighting that I've ever seen was in Center City Philly, a short dark skinned woman that had boobs so big that she rivaled "Ms 17th Letter[Y'all know who I'm talking about]," with a similar body frame. No I don't have pics of that this was a while ago.
Sounds like you spotted Kim Gorham aka Ebony121800 in Philly. First saw her on her lunch break around 2003 in a pink sweater. She was legendary an easy LL M cup.
