I could probably write a nice flowing adventure story about how everything was just so, and had all fallen into place (timing was iffy, what with out-of-town travel and such).
Well, we overslept by an hour or so the morning of the proposed training (fortunately group, and the instructors knew I was balancing a house of cards getting everyone in one place).
But we were going in time to make it. Got everything loaded and jumped into the truck and headed out to the range at a "quicker than usual" pace. Only to get halfway there, and realize that...
The range bag was still sitting at the end of the bed at home.....
We decided to have a nice leisurely breakfast together, and we laugh about it to this day.
