We actually did the opposite of Nyxie - were looking at Keene Ranch vs. Bell Mountain and ultimately picked Bell Mountain.
This was the only neighborhood we found where we could have horse property in a larger-lot community, quick freeway access, and really good internet + phone connection (important for us to be able to work). We found that Keene Ranch had pretty poor connectivity and was quite farther to get to the freeway.
We actually love that water is centralized (pumped from multiple aquifers, so no worries about well maintenance or well drying out).
Haven't had any issues w/ HOA - if anything, the Design Committee has been really responsive and has approved all of our enhancements. Love our neighbors, the views, and miles of trails!
