After our trip to Denver a few weeks ago, I noticed a charge of $12 from Alamo. I figured they were just catching up something on the amount I paid. But I looked at it closer and noticed is was a toll road charge.

I took a short segment of a toll road but never saw a booth, never thought about it again. Turns out they have license plate readers and bill the rental company who in turn marks up with a fee then charges the customer. I found, and was somewhat horrified, by the following article explaining the racket. I don't run across toll roads where I live so this is new to me.
