Help Chris Evans' favourite charity

This coming March, several members of the Facebook group, We ♥ Chris Evans, are travelling to New York City to see Mr. Evans in his first turn on the Broadway stage. After that, we'll be carrying on to Boston where we would like to be able to make a donation to Chris' favourite charity.
This charity provides a haven for children and their families while they are receiving treatment for cancer at Boston hospitals. Their mission is to provide a comfortable home away from home for children to be with their families and other children going through the same experience between treatments.
