Can anyone tell me historically where the 70-75s play in the Rock'n Reno Challenge Cup ?
LeeM, you can actually answer that question yourself from resources on this site. If you look at the bottom of Tournaments, there is the Tournament Archive which has that information for many years.
LeeM ... I'll save you the research project ... For at least the past 10 years, the answer has been the same: Facilities in Reno/Sparks, which include the [1] Reno Softball Complex at Rancho San Rafael, [2] Shadow Mountain Softball Complex and [3] Golden Eagle Regional Park ... It will remain that way later this month ... Good Luck!
