LC,
I have a slightly off-topic question for you. On a recent trip on I-80 between SLC and Park City (US 40), I saw a truck runaway ramp. For those that don't know, these ramps are there to stop a runaway truck going downhill, out of control.

The ramps always go slightly uphill, and are usually dirt, and lots of it. It's meant to stop a truck.
My question, did you ever have an emergency and have to use the ramp?
