Last year we saw some of both, rubber tires & spoked wood wheels with steel rims. They had some original old antique wagons driving around but did not race them. They have a "breakfast,lunch, dinner" wagon. An old original chuckwagon serving meals all day into the night till no ones hungry anymore. All cooked outside over a fire.
We had a good trip and saw some wild horses & Tx Longhorns running wild in the mountians, not used to seeing that in Texas
