Besides the connection I mentioned before made at my nephew's wedding, we were seated next to another guest, whose sister lives a block from our house.
Moonrabbit does some part time work for a small non profit group that uses child labor to restore wetlands. That is under the umbrella of a larger non profit nature restoration/protection group, which just announced yesterday that they had purchased the SF Bay Aquarium. At the press conference/reception she met a man who works at the aquarium, who looked a bit familiar. Eventually they realized he lives across the street!
