Help wounded Vet get active again!

Due to two blasts to my head during a tour to Iraq, I have lost my sense of balance. Im an avid bicyclist and have not been able to ride my bike since 2005. I would like a recumbent trike to be able to get out there and ride again and regain some independance. However these trikes cost around $3000 and more. We live on a fixed budget of disability payments and are having difficulty with this on our own. Please help me get back on the road and trails! Thank you for any contribution no matter how small. It all adds up.
