Noticed this thread after posting about the upgrade efforts here.
This particular rally is scheduled on the same dates as Bikes, Blues, and BBQ, in Fayetteville Arkansas. I live in Fayetteville, and split my time between volunteer efforts and riding with others. Last year I didn't ride as much, just during the day and hung out at pubs Saturday night.
Pig Trail is technically south of Eureka Springs, the north end starts at Brashears, and ends at I-40. It is extremely tight at first (a couple dangerous 5mph curves) but smooths out on the southern end. The road north of brashears, going to Eureka, is actually more popular.
It's going to be interesting, folks are going to have more choices.
