Tucson John, How about a Phoenix-Tucson Challenge meeting at the Dairy Queen in Globe?

You can buy us all an ice cream cone and your group and ours can separate for respective runs. We could follow 188 up to 87 (maybe lunch at Jake's Corner) and back to Phoenix. You could run the ring to Superior and south to Tucson (maybe lunch in Hayden.)
Date? How about March 22? Open to other suggestions.
