I saw that today. Sucks, but it sounds like he's still moving in the right direction overall. I spent a couple days in the hospital after my back surgery a couple weeks ago. I can't even imagine being there for weeks (coming up on 2 months) and dealing with the pain and frustration I'm sure he's going through.
I have seen some interesting work with prosthetics recently so hopefully he'll be able to minimize the impact of the loss in the long term.
I'm sure it's a long way off but, if Wes is eventually willing to share, it would be interesting to hear his account of the incident. Having seen the footage, and the long time of not seeing him come out of the rig... I think it could be a great thing if he felt comfortable to share what went wrong, or why he wasn't able to get out of the car quickly. Might save someone else from having the same issue.
Of course that's completely up to him if he ever feels up to talking about it.
