Last summer we rented a car (Toyota Camery) one way with Hertz from Fort Worth, TX to Reno, NV for $900 for a month.
That same deal is still available in both directions today. For a one way trip from Reno to Savanah, GA it is about the same. But for a one way trip from Reno to anywhere in Florida it is between $160 and $200 per DAY.
Why is it so cheap to drop off anywhere except Florida… even dropping off in Portland, Maine is MUCH cheaper (70%) then dropping off in Florida.
