Poobah Mitzvah? I did the same thing, sort of. My two kids got to go with dad on a domestic adventure of their choosing when they were 5, 10 and 15.
Cassidy Kate: age 5, chose Atlanta to see Giant Pandas (she was disappointed in their relatively diminutive size)
age 10, chose Hershey, PA for one obvious reason.
age 15, a wild Northwest driving tour from Chicago to Washington state taking her brother along.
Samuel Byron: age 5, chose Boston to eat fish and go to the aquarium. I made him do all the subway navigating and he excelled at it.
age 10, chose Los Angeles. We watched the White Sox win the World Series in a Country & Western bar on Sunset Boulevard.
age 15, a pie tour with his sister. Ate nothing but pizza and dessert pies for 10 days from Chicago to Atlanta then back in an elliptical tour so we could go to Cleveland and the Rock-n-Roll museum.What do they remember most? Pie and chocolate.
