Old thread revival.

I think in these modern times a "bug out bag" will be a suitcase as your more likely to end up in a hotel than the wilderness. I've known a couple families that had to leave their house because it caught fire, and others that had to spend a week in a hotel during the winter due to power outages/furnace failures.

Take what you have, suitcase, duffel/gym bag, school backpack and start there. Put in some food/water/change of clothes/ toiletries, cash, etc. Pick a random weekend and "bug out" to a hotel somewhere as a surprise minivacation. Pack a small notepad and make a note of things you need/forgot/wish you had. When you get home start a plan to rotate stock in your BoB and add things you noted.

Then as you add/upgrade gear look for gear that can double duty with a hobby (camping, hiking, etc) so you can practice and share cost.
