Being a paraplegic would really change the composition of your PSK! While the Rule of Threes applies to everyone, not being able to walk would present some unique challenges. A mechanical breakdown, while inconvenient at a minimum for someone that can walk, would be especially problematic. I can appreciate the fact that I wouldn't want to allow my disabilities to dictate my life, but I'd be sure to have a PLB in such a situation. Doubling up on the signaling stuff would be a wise idea.

And maybe steel toed boots...something crossbow proof!
