re: Most unsuspecting place you've run into somebody you know?

In our case it wasn't the place so much as the timing. One Mardi Gras maybe 20 years ago, there was an aircraft carrier docked in New Orleans and they were allowing civilians to come on board and tour. My husband, son, and I walked down to the dock from the French Quarter to see the ship, along with a hundred or so other people. As we were traveling between decks on the huge aircraft elevator, we looked behind us and there were my MIL and her cousin.

As my husband said, if we had tried to plan to meet her on the ship, between the crowds in the Quarter, the number of people on the ship, and lack of cell phones with which to co-ordinate on site, it never would have worked.
