Hi again Neil,
I have read this whole thread and after reading the last few new post's there are a few points I would like to make.
I can't help but feel perhaps some people have the wrong attitude when it comes to this subject. I'm not singling you out Neil.
Now I would never begin to say how tough it is to be in a wheel chair, I could only imagine how hard it would be!!!
But how about a positive mental attitude towards this subject.
Find a club to race where the people are very nice, yes this can involve a lot of driving, get involved, race as much as possible, even if you have to do it off the ground, yes it's gonna be tough, but as you get to know the members of the club talk to them about a disabled ramp, and see if one could be built!!!
This may mean trying a few different clubs or a few different sections.
Now you may read this and think "what a load of sh1t" I am talking.
But the truth is Neil, there is no easy answer!
But don't give up on the sport you enjoy because you can't get what you need/want or because the people you have been dealing with aren't giving you the answers you want. Get out there and make it happen.
