I have a friend who has RLF and because of his work, he travels all over the country. He uses a cane and has no more difficulty than anyone would who is going into unknown territory. He tried to use an optacon, but wasn't successful enough to stay with it. I think that in this case there may have been two things that made it more difficult. He didn't have to learn it in order to get a job as I did. Also, some trainers are far better than others.
