One sure fire way to make this particular mom happy is a visit to the New York Botanical Gardens. Located in the Bronx, it's an easy drive from Westchester and Connecticut, and an even easier train ride away from anywhere in the city. It's a great place to get ideas for your own landscape and gardens or just to enjoy the peaceful beauty of the place. The architecture is not bad either. I love the glass conservatory and the Beaux Arts main building.
