I also work about 30 miles from home.
I carry basix essentials with me at all times, always within arms reach (even at work, I work at a desk)
I use a very small and compact set up at this time, I will be making changes and adding more.
As it sits right now:
-Mini Messenger Bag
--Compact First Aid Kit
--Surefire E1B LED Flash Light
--x2 Chem Light (8hr Green)
--x4 Surefire Batteries in waterproof container
--Gerber M600 Multi Tool
--Pen/Pencil/Sharpie/Notepad in case
At all times I always have a knife on me and sometimes my Surefire E2D LED Defender
