[nfb-talk] sonar for blind

[Karen Rose]

With no vision, I am told that I left my house on my own to deliver something I had found in a cupboard to a neighbor, at age 2.  I guess no one told me I needed mobility training, echolocation, or anything else, just the spirit of adventure.(LOL)

Chuck, that’s the real travesty right there—the notion that at age 12 
you finally need to start learning how to walk on your own!  This is 
a pet peeve of mine (I have so many!) so I’ll stop before I get 
started.  *grin*
