Help Purchase Freewheel Attachment

In April of 1996 Suzanne Revell was a senior in high school with a full-ride scholarship to the University of Oklahoma for gymnastics when she suffered a fall from the uneven bars in practice that left her paralyzed from the waist down.   She spent a couple months in the hospital and in rehab learning to live life in a wheelchair.  
Life hasn't been easy since with the multiple procedures she still has to have several times a year and the loss of loved ones.

She casually mentioned on Facebook the other day that she'd like to have a FreeWheel Wheelchair (https://www.facebook.com/LivingSpinal/videos/1178808578919441/?fref=ts)
Attachment to help her get around in her chair better on long outtings and while she's traveling. She has so many friends from school that it shouldn't be an issue for us to all chip in a few dollars to help her with this. 

She's recently engaged, about to buy a house and it's close to Christmas. It can be a Christmas engagement house-warming present!
