I am beyond upset....
Probably because I am too tired now, but anyone have idea of how to stop that???
I'm very familiar with Highway 90, all the way from New Orleans to Lafayette, so I feel your pain.
The best way to deal with porpoising is to either speed up or slow down until it (mostly) goes away. Given the abysmal state of the highway system in Louisiana, I'd definitely recommend slowing down rather than speeding up.
Also, you might try detouring. Instead of taking Highway 90, you might go north of I-10 to Highway 190, at least west of Baton Rouge. That has some bad patches as well, but isn't as heavily trafficked, so it isn't as badly worn overall.
