Typically it marks the beginning of summer.
Young capitalists and eager entrepreneurs dot the corners of suburban streets with lemonade stands, car washes and bake sales.
But rarely do you come across a group of young women, where the ring of a Barbie cash register marks another dollar earned for Gilda's Club Capital Region of New York.
A cardboard sign in front of their stand reads: Please! Support Gilda's Club.
The girls, who live in a development across Albany Shaker Road from the South Colonie School campus, hold car washes, sell cookies and Kool-Aid, and have organized a collection of cans and bottles, with proceeds to be donated to the cancer support group.
They have taken it upon themselves, with a nudge from their parents, to continue their corner street stands and expand their fundraising into their schools.
The girls' philanthropy began with little more than $50 in profits from a car wash and lemonade stand sales.
The idea to donate the earnings came about when the Cronin sisters, Julia, 7, and Lily, 5, couldn't decide how to divvy up their profits with fellow entrepreneurs Elizabeth "Lizzy" Green, 7, and Emily Green, 10.
"We just wanted to do it. We thought we would get a lot of money, but it didn't split even," said Julia.
The girls decided to donate the money, and after some discussion and a suggestion by Julia and Lily's mother, Alisa, they chose to give to Gilda's Club.
Soon profits from the car wash, lemonade-stand dollars and neighborhood donations brought the total to just under $100.
Now, more than $100 later, the Cronins, Greens and FitzGibbon sisters have pulled in other neighborhood girls to help with the fundraising. They also have expanded their bottle drives in the neighborhood and their respective schools.
In between sales at their bake stand last week, the talk was of other fundraising methods.
