Learn me Dallas Neighborhoods, wise Texans!

I'm taking my law-talking talents to the land where everything is bigger---specifically, Dallas. I need help picking out towns/neighborhoods

- My wife and I would like to rent / buy a house north of Dallas.

- My wife and I prefer rural communities (we can deal with HOA type sitches, but more space the better) -- I have a full compliment of really loud ass musical instruments. I can play Lyle Lovett like a mother-f, but I'm thinking that neighbors may shoot me.

- I'd like to be within a 30-40m commute (regular not effed up traffic) to the historic district of Dallas.

- I'd also like to hear anything about living in Texas, restaurants in Dallas, whether boots and suits is truly appropriate, will I be shot if I wear a bolo tie?
