This is something that is often–sometimes hotly–debated in the blind community. A lot of times, when you go to amusement parks, if you carry a cane you can cut to the front of the line and go first on all the rides. The last time I was at a leadership seminar for the National Federation of the Blind, we had a roundtable discussion about this issue, what we thought and what our experiences had been.
This is something I never really encountered growing up. My family went to amusement parks pretty often, but since I don’t use a cane, no one ever approached us and invited us to the front of the line, except maybe when we went to Disney World, I have some vague memory that it may have happened then.
