Harris County Toll Road Authority Exccessive Fees Houston Texas

I was in Houston, TX over the 2015 Labor Day weekend.  I unfortunately wound up using a toll road that is managed by Harris County instead of TxTag.  TxTag charges a $1.15 admin fee for sending an invoice if you use the roll roads they manage and you do not have a tag.  overever Harris County charges $11 plus the toll for every time you enter a toll road if you do not have an EZ Pass.  I am in Houston maybe twice a year.  I am not going to pay $15 for a tag, establish a $40 minimum balance and attch something to the window of my car.  Harris County needs to provide a way to pay when you use their roads (sometimes it is to late to get off the road) or charge a reasonable fee like TxTag now charges.  My $4.75 worth of tolls turned into $37.75 becuase I accessed their roads 3 times and was charged an $11 fee.  This was the amount they charged on my first bill and the only way to get the fee waived was to purchase an EZ Tag.
