Wonderful views of New York...and imagine our surprise to learn first hand that the water fountains "talk" to you, saying things like.."How do I love thee..let me count the ways"
And when I looked into the bathroom mirror while washing my hands, it said "I like your blouse!". lolol
And like you, I will be in moi territory in spirit only...I know they will have a wonderful time celebrating an anniversary in addition to enjoying that beautiful part of our country.
