Reminder, if you're going to be driving cross country on the weekend before Labor Day, the I80 and I35 are going to be over policed, and they are in the top ten most dangerous freeways anyhow (#s 7 and 10 of the top 10 most dangerous list)

The I-80/I-35 Challenge, Border-to-Border Traffic Safety initiative covers 4,400 miles of roadway from California to New Jersey and Minnesota to Texas and was planned to coincide with the “You Drink You Drive You Lose” (YDYDYL), national enforcement campaign.

It turns out, police departments get involved to get federal funds, and sure, the extra ticket and car seizures don't hurt either
