Sierra’s graduation

I have a 18 yr old sister named Sierra who will be graduating from high school  this year. She is what every parent dreams of having as a daughter. She is very smart, self motivated, goal oriented, and focused individual. She's very involved in school and is an exceptional student She also  runs cross country track.  She will be going to college this fall and wants to major in marine biology. She has been offered many scholarships because she is a straight A student and takes advanced placement courses. She is such a hard working young lady I really feel that she deserves a chance to travel and broaden her mind before she goes off to college and gets focused on her new and exciting career.  I am a single mother with 2 children of my own and I would love to send her on a graduation  trip before she starts college. As a family we are not financially able to sponsor her trip fully.  So would appreciate  anyone who would be able help Sierra in her travel endeavor.   Any and all donations would be greatly appreciated. Thanks in advance.
