Answer : A bunch of them.

Here is a site based on the idea in your thread.

Example of a story they posted :

Woman turns 107 and her wish was to participate in a parade. The town had other ideas.

All Myda Lewis wanted for her 107th birthday was to ride in a convertible in a parade. Her community, however, decided to give her much more than that.

When her birthday was steadily coming closer, the hospice caregivers at Westhaven Nursing and Rehabilitation Center asked Lewis if there was anything special that she wanted for her birthday. She said that she had two wishes – and one of them was to cruise through a parade in a car with the top down.

Determined to fulfill her wish, the nurses started contacting people in the community and asking them to come out onto the street when Lewis drove by on her birthday. They created a Facebook event page with details about Lewis’s cruise, and it immediately garnered over 800 confirmed attendees.

With the entire community of Stillwater, Oklahoma crowding the sidewalks, Lewis’ birthday car ride blossomed into a fully-fledged parade.

She said, her second Birthday wish also came true as her second wish was for everyone to be happy.
