Hi Kd;
You should be supplied with a chair free if you require one so ask again.
You do meet a lot nicer people that try to help you. I have to use a talking machine and that to fascinates people, especially the younger ones.
Doug, most wheelchairs feel unsafe on side slopes and are not good on uneven ground.
I have a four wheel one that can go over uneven solid ground but I have to go very slowly because of the ride.
The six wheel ones look to be possibly better for general use.
Love Terry
