Yes that's ture. ISU hosted the 1961 NCAA Tennis Champions on Forker Courts (men's only, no women's championships were held until 1982).I bet no one would believe that ISU once hosted the NCAA tennis championships.
Copied from Cyclones.com, here' how the ISU Tennis program uses its facilities.
The Cyclone tennis team has two facilities at its disposal. Conveniently located across the street from the Lied Recreation Athletic Center on central campus, the Forker Courts serve as the outdoor home of Cyclone tennis. When inclement weather moves matches and practices indoors, Iowa State utilizes Life Time Fitness in Urbandale, Iowa.
I agree it definitely needs an upgrade. I hope some rich tennis-loving donors can make a contribution. I myself love watching tennis and I have watched a lot of pro matches especially the grand slams. I'd really love to see ISU have a strong tennis program.
