It takes right at 4 hours to get to KAF from Dallas while staying within the speed limit.
This makes the trip only about 30 minutes longer than from Dallas to the old Norman
landsite.
By the way: do not be fooled by all those lovely highways on the map....
even in perfect driving conditions (good weather, no traffic, no accidents,
and no road work) they add at least an hour to the trip.
Here's an overview of the trip from Durant to KAF. The KAF grounds are
identified by the yellow star at the top of the map and Durant is located
neear the bottom of this map.
About half the trip is 4 lane divided highway and about half the trip is 2 lane lightly traveled highway. If I were coming from Ft Worth or Lewisville, I would go up I-35 to north of Ardmore and take the Hwy 7 exit to Sulphur and then take Hwy 1 to Ada. From Ada, take Hwy 99 to Stroud. That should save at least 1/2 hour as compared to taking I35 to I44 to Stroud.
To get to the King Arthur Faire grounds from Stroud:
The IFGS compound is a ways in the Faire Grounds - about 1000 meters from the main gate. Head northwest from the main gate, and the IFGS area will be to the left of the Troll Bridge.
