For the Memphis area tournaments, when you ski at Summers Lake, you are skiing in the Southcentral Region. Hilliard's (Crews) lake is in TN and is in the Southern Region, but Summers Lake is across the state line in MS. We have 2 tournaments before Regionals (late May and late June) and 1 after Nationals at the end of August. Roebuck can give you the exact dates. Cedar Ridge (Jackson, MS) also runs class C tournaments along with most of their record tournaments.
