UPDATE: Cambridge

At the
head of the creek (38.564655,-76.071536) is Mercado Latino Carniceria which has excellent meats. I also picked up fruits and veg plus other fun staples. All excellent quality.
It is literally across the street from the
water. Could not be easier.
Nearby are other stores that could make for a more comprehensive stop. SImmons Center Market is a couple blocks away which has a basics.
