One thing to think about is if you have no enemies you also wont get easy loot. Popping a few skeetoes every day, plinking the 2-3 lox hanging about, and even fulings will increase your bow skills and give you lots of pies & needle arrows. You just need decent earthen walls and a little ditch around your base there. And your idea of making the base at a convergence of biomes is a good one. Makes events pretty fun.
