Mileage Run Discussion - Help - JAX DL needs 12,000 miles

Two days to get 12,000 miles in the states any suggestions on best runs are greatly appreciated. Best scenario I have found so far

DAY 1
Jax - ATL - Bos
Bos - JFK - Sea
Sea - JFK

DAY 2
JFK - LAX
LAX - ATL - JAX

Any better ideas are welcomed!
Thank you!!
