* Read gun books
This is a beginner quest. Once most new players get those books, they are no longer interested in doing these starting quests. They've moved on.
* GUN runners, not PUNCH runners lol
Marshall teaches Boneyard Guard, and includes HtH there. So what really makes sense is to include HtH this way too, or disable quest for HtH at quest-giver, rather than allow people to start a quest they can't even do yet only to hit a hard stop. If people start a quest, and hit a dead end, they will surely post about it on forum, sometimes calling it a bug. So this suggestion will likely clear some confusion and lessen requests for help.
