I haven't completely explored the area around Hub City, but "Epsilon" is a good seed. The main reason? There is a second Hub City NE of 0,0. I've also found Towns West of Hub City and one East of the second Hub City.
Personally, 2 Hub Cities very close to each other is worth the price of admission alone. The only gripe that I have is that there seems to be a lot of water to the south of 0,0.
I got lucky, I started near a crossroads with a Diner and Crack a Book. I can't remember exactly what I got from the Crack a Book, but I do remember cheering about it. It may have been Crossbow and the Minibike book.
