I didn't learn this tonight, but it was really reinforced. @Tam, @Earthling789, @Jeffb, @Bebop, @Compenstine, and countless others drilled into my head about backups, and backups for backups... tonight it paid off.
I had to work late and we were rushing to get out the door at the office. I jumped into the car and headed home. I reached down for my trusty NEBOX, and it wasn't there. I had a flash and saw it setting on my desk. I was 10 - 15 miles away, and I don't have a key. I thought about calling the boss and turning around, but he was rushing to an event for his daughter. It wasn't a problem. I reached in my laptop bag grabbed my backup. It was dead. No problem, popped a fresh battery in and drove home. My current backup is a Wismec Presa 75TC with a Crown on top. It doesn't vape like my NEBOX. No problem again. I get home rebuild the RBA grab the new backup off the shelf and it is just like I didn't leave one at work....all is well and I am calm.
