Las Vegas:
215/Rainbow westbound - It's a HUGE curve and people tend to go really fast around the blind corner where cops DO sit by the underpass, just waiting for idiots who are going 90mph+ in a 65 mph. Not a speed trap, just slow down and follow the damn limit.
McLeod between Tropicana & Hacienda - There is a PARK there. Yeah, slow the F down. Families cross the street to get to the park. I drive down that road a couple times a week since we live about a block from this location.
Desert Inn & Maryland - There are a lot of apartments, a hospital, and a mall right at this intersection. Slow down.
I could go on and on and on...
That website just seems to be full of whine babies who all received speeding tickets.
