Hey, am new here but just wanted to share my entry to the sport as someone with the disability (paraplegic)
Here is a little video of my recent experience on new brighton beach in CHCH, NZ.
Have been lucky enough to have the help of Gav Mulvay to set up a buggy with hand controls and am having a great time with it. (thanks gav).
It is a pretty simple and easily removable mod that seems to work great.
