I also highly recommend looking around Boalsburg...along Penns Valley Hwy (SR 45 north of US 322) there are a ton of new developments going up with what looked like large lots when I was last there (roughly southwest of Centre Hall/Old Fort...not near or past there).
Then between there and Lemont is a large swath of newer developments.
I also think there were a few developments going up along US 322 east of State College where it becomes a two-lane road...and I know there were a lot of homes with very large lots there.
Good luck in your search.
