FYI

When you're going through the tolls between Oklahoma and Texas there are exact change only lanes so you can throw your change and get through quicker. Don't be fooled because the sign reads "Takes 25 10 5 and 1 cent coins." If you were to throw 40 cents worth of pennies the machine will not count the pennies. Then you have to honk until the toll lady comes out and informs you that it clearly doesn't take pennies.
