Sandra Mardenfeld’s favorite travel experiences are hot air ballooning over the Australian Outback, shopping at Camden Market, and milking cows in New Zealand. Now, as a mother of four children, her travels are more local--including most of New York State. She has been a Girl Scout leader for more than 16 years, and her eldest daughter is working on her Gold Award. Sandra has belonged to a Monday night yoga group for 17 years. She also loves to read, and she belongs to a book club.
