I went thru toll roads in CO last July (2011) which had no toll booths. It took them a couple of months to send me a bill for $11.80, which I paid online. Apparently, they had a pic of my license plate, lol…
You’re lucky. If you did that on the East Coast without an EZ-Pass, you’d be fined $25 per incident in addition to the toll. Fortunately, most (all?) toll roads still have cash booths.
