[David Litts],
At the risk of sounding condescending, I totally admire your dedication. Most people will look for any excuse to NOT do something. You, on the other hand, are letting neither disability nor finances keep you from achieving what you want. Hats off, sir. I have nothing but respect.
One quick note about your health. While you may be at a disadvantage with your eyesight the way it is, you can certainly use all of your other senses to help maintain situational awareness. Furthermore, to be honest, once that SOB lays his hands on you it’s all pretty much feel anyway (believe me, when I have a training knife or gun stuck in my kidneys, I ain’t looking, I’m just reacting!) As far as your lung capacity, don’t sweat it. It just gives you all the more reason to end the situation quickly… which is exactly what SDTS is designed to do anyway.
I think you may have found your new home, my friend.
