Coffee Creek is good we looked at a couple houses in there. Anything really west of Santa Fe will be newer with schools in Edmond or Deer Creek, both good. I would hang around the area until a train goes by, sometimes they can be loud even though the track is a couple miles away.
The more North and West you go the newer it will be and possibly get a little more land. When we moved up to Edmond we were surprised at how small the lots are, but seems like that is everywhere. We live in the Valley and like the area. We would like to move to somewhere like Fenwick that has a pool, but that isn't a huge deal for us.
