If I could reach the town firstly, I would probably travel the wasteland looking for any good loot that I can sell back to the town. I mean, the only real skills I have are a good knowledge on firearms despite never being near a real one, the basics of techniques for sniping from reading a book written by a British sniper & a Cert II in both hospitality and IT that I haven't had to use yet. The way I see it, the best I can do is loot the surrounding countryside, assist the town in gathering supplies and making sure that nothing dangerous comes within a good two kilometers of the town.
