I made my very first Die Drop Table, and I want to share it with you ( it is a pay-what-you-want-product). Naturally, it is something Post-Apocalyptic as this a genre I like a lot. The little thing you are going to find below will help you to generate an encounter with (other) human survivors by the drop of three dice (a d6, a d8 and d10).
The sum of the d6 and d10 tells you how many individuals are encountered ( 2- 16).
The location of the d10 (the field it ended up in) tells you who they are (e.g. marauders, nomads, etc.)
The location and result of the d6 tells you what they are currently doing (most of the time, the characters will encounter people who are traveling themselves).
The location and result of the d8 tells you something special about this group (e.g. infected, riding on horses, demanding a toll, all dead, etc.)
Et voilá! There is your inspiration for your next encounter! If one of the results tells you to generate a second group of people, just roll the d10 and the d6 to determine who this second group is and how many they are (see above).
