Thanks.
The mechanical engineer in him is definitely back - you should see all the bungie cords for his water bottle, carabiners for keys, tools, etc, pouches for his cellphone - attached all over his wheelchair.
That sounds so awesome! Happy to hear he is so much better!

It reminds me of something I say a lot - "I have 6 pack abs.....but they're all 2 liter bottles!"
