Don’t put all your dollars in one place especially when visiting or traveling through sketchy areas. An empty Chapstick tube can easily store some emergency dough. Hollow out your own you can find them on Amazon.
The same goes for your truck or van keys. Always have an extra set stored or hidden away. Either keep a spare set in your spouse’s pocket or even better yet, have a locked set of keys in a lock box that locks to your van or truck.
