Our tourguide, Mat (I hope I remember his name correct) was really kind, really funny and had great stories. He was kind and took care of us. He drived the car softly.
The places we visited was awesome and inretesting. So the tour was ok!
The only problem I had is that we did not get e-mail, or aby warning that the tour starts 30 mins. earlier, and therefore we missed it and had to postpone it next day. Therefore we had extra outcomes (whole day parking fee and the gas we needed for get to Dallas from Denton)
