I agree with andersaa about the recruiting on a broader basis. When I started out in D3, I more or less stuck to the 300-400 mile range as well. What I realized, especially as I was able to build William Paterson up, is that if you have a high prestige, can be smart with your money, and have the good fortune of being able to build a larger bankroll (i.e. through post season play), you can really expand your reach even at D3. Of my 11 scholarship players this season, only 4 would be considered "local" (NY NJ PA). I have a guy from each of North Carolina, Arkansas, Oklahoma, Arizona, Idaho, South Dakota and Florida.
Key to D3 recruiting at distance is to not overstep your prestige if a possible battle looms. It's just not worth it.
