This is a great shuttle service. They will take you from Tyler to the Dallas airports for just a small fee. One of the good things about this, is that you don't have to find parking they just drop you and your stuff off, plus not only that, you don't have to drive in Dallas traffic.
They also go from Tyler to the casinos in Shreveport, LA. This is great so that if you are out drinking and gambling you don't have to drive yourself home, you can just get on the shuttle bus and come home.
The down side to both of these places, is that you have to go when the shuttle goes so you might be waiting in the airport or get to the casino earlier that you need to be.
