Echoing what others have said... low traffic roads, good luck finding anything that isn't chip'n'seal once you get outside the suburbs. South from Dallas, you might get as far as Mansfield or Midlothian, but really anything more than 5-10 miles south of I-20 has a high chance of the stuff.
Best thing to do about Chip'n'seal is bigger tires. Personal experience, if you can fit 28-30mm tires in your frame and run tubeless it cuts down the buzz a lot. I run 25's tubeless at 75-80psi on my Allez Sprint (a notably stiff frame) and it's more comfortable than any tubed tire I ever used on a carbon road frame, and fairly tolerable. My aluminum CX bike has 33's at 50psi and that makes the stuff feel like the buzz from a cell phone.
