Thank you for pointing those out in the rules.
"If the Raider Stronghold HAS been drawn..." is correct.
"Spend to reroll ANY roll or add a +1 to any roll..." is correct.
I ended up color coding the Items, Traits and Companions. I should probably mention that color coding scheme somewhere in the instructions. Red has something to do with Combat, green has something to do with Survival, Brown is generic and move, Grey is defensive and Purple is special. The Events and Missions follow this color coding as well.
I've gotten 19 Fame focusing purely on Salvage Sites with a little bit of Scouting before, so it is viable approach. However, it is better if you have Traits/Companion bonuses that give you more than the standard d4 of salvage (extra Water Ration or salvage helps a ton). It becomes an even more powerful approach if you can get extra Reputation for turning in green rings, which is possible with a Trait.
I'm happy to hear that you are having fun! Please don't hesitate to keep the questions coming if you run into anything you aren't sure about. They are very helpful to me as well!
Thanks for the tips (they worked!).
