[il-talk] So that the Blind may cross Streets Safely

Tue Nov 11 16:26:06 UTC 2008

The Federation needs to be out in force with this issue.  We need 
mainstream media coverage with this issue.  I can see some dangers with 
this.  Not everybody will want to shell out money on a new cell phone 
nor should they be compelled to.  Not everybody wants a cell phone.  We 
need some face time on mainstream media.  These subtle compromises by 
"shighty" need to be dealt with before they mandate the ever popular 
laser cane and tear up sidewalks and put wires with sensors down.  I 
become very appalled everytime I read these stories.  It is time to 
mobilize and strike back and do it swiftly.  Our very sovereignty is 
under attack by these nare do wells.  I am tired of these false 
custodians dictating to me about wheree to sit, wheere to stand, and 
most important to this article, how to cross a street. 

Sincerely,

Mr. H.
