BoB and my war/plague box? No. But my ditch kit and a lot of BoB goes with me camping, so it has been tested under "training conditions".

My EDC is my GHB. Last winter, just after the new year, my vehicle had some issues and it reached the point shortly after work that I felt I could not safely get home with it. I got it to my garage (about a mile and half from work), left them a letter and the key and walked home. Spent a week and a half hoofing home with the same kit (could catch the bus in in the morning, but I'd miss the next to last bus and it was an hour wait for the last one, so the heck with it, walk the hour and a half.)
