I travel using structure discovery methods. I go to new places without a set of instructions on how to navigate the rout from point A to B.

Most meaningful, I would say doing a route or getting somewhere a client thought was impossible for them. Sometimes it could be a small as crossing a lighted intersection. Other times, it could be taking the subway.

I'm really interested in this because I have become a sort of semi official instructor to a couple of people because they wouldn't talk to anyone else. That's sort of flattering but I've never had any idea if I'm doing it right, beyond the fact that what I'm doing has kept me alive for a long time. Most of it is calling people and making arrangements, anyway, and that's not specifically a blind person skill it's just a life skill.

Are there lots of other people instructing cane technique who are actually blind?

The most meaningful for me was transit use and route planning, mostly because I was new to public transit. It also curbs the dread when you start to think about how you're going to get to appointments, etc.

I am not visually impaired or blind but am a habilitation specialist in the UK. I assume you are state side?
I too am interested to hear answers to this question.
Does the fact you are called an O&M mean you focus solely on mobility and orientation?
Do you support independent living skills?
