If you enjoy sending mail, you might want to consider signing up for Send Love Today. This nonprofit organization sends mail to kids with brain tumors.
If you go to their About Us section you will find the email address and postal address of the two ladies who run this wonderful organization.
For the next two months I will be sending mail to 11 year old Claire along with one or two other volunteers. All you need to do is let Linda or Sandi know who you are and that you are interested in doing this and they will send you the information to get you started.
