re: What’s the dirtiest US city you’ve been to?

The city with the worst roads in the US is Houston, TX right west of downtown, not in Louisiana. I've lived in the 3 biggest LA cities and compared to specifically the Montrose/Midtown roads in Houston, they are pristine.

Drive down Westheimer, Alabama St, or Richmond Ave in Houston and the neighborhoods in between, and your car value will drop $1,500 by the end of the week. 3rd world country bad. Not the interstates, but the roads in this area.

You'll no doubt come across 8-12 inch drop offs or potholes in this area on any trip. People in Louisiana automatically defer to thinking everything in Texas is nicer, but this part is not true. That and the DMV's here are a much longer wait, with lines going hundreds of feet outside the building sometimes.
