Mobilty Scooter Fund

I want to buy a mobility scooter for my wife.  After years of standing at jobs her knees have become so painful she can barely walk around the house.  When I take her out shopping she is limited to stores that provide mart carts.  Lots of trips she is forced to wait in the car.  We have tried getting one through insurance but have been given the run around for months.  This would allow her the freedom to go to the park or shop where she pleases.
