USA-Swimming is divided into 59 separate LSC's (Local Swimming Committees). Many, like North Carolina Swimming, are more or less consistent with state lines. Others, such as the Gulf LSC are only a major city (Houston) and its surrounding towns.
The Southern Zone is comprised of 15 LSC's:
North Carolina Swimming, South Carolina Swimming, Southeastern Swimming (Tennessee, parts of Alabama and Florida), Georgia Swimming, Florida Swimming (central Florida), Florida Gold Coast (Miami area), Mississippi Swimming, West Virginia Swimming, Louisiana Swimming, Gulf Swimming (Houston area), South Texas Swimming (Austin, San Antonio and the Rio Grande Valley), West Texas Swimming (Midland, Lubbock, parts of New Mexico), Border Swimming (El Paso area), North Texas Swimming (Dallas area) and Kentucky Swimming.
Each Summer these 15 LSC's compete at the Southern Zone Championships. The meet moves around, but is often at Georgia Tech in Atlanta, University of Houston, Fort Lauderdale, Orlando, or San Antonio. Teams are selected with seven 11-12 males, seven 11-12 females, seven 13-14 males, seven 13-14 females, 10 15-18 males and 10 15-18 females.
This summer's event is wrapping up this morning with an Open Water Swim. This swimming portion of the meet was held at Georgia Tech.
Wednesday evening Andrew Henry placed third in the 13-14 men's 200 free with a new team-record of 1:59.66 at the Southern Zone meet at Georgia Tech in Atlanta. Andrew then posted a 9th-place finish in the 200 meter breaststroke. Keary McClernan placed second in the 200 meter breaststroke with a personal best of 2:38.40, just off the national cut of 2:38.09.
On Thursday evening Andrew added another 9th-place finish in the 400 meter IM after narrowly missing the finals of the 200 meter backstroke with an 11th-place finish in prelims. (Tech is a ten-lane pool)
On Friday Keary added another second-place finish and another LTB (lifetime best) with a 1:13.77 100 meter breaststroke swim. Andrew also added a 6th-place finish in the 400 meter freestyle with a LTB and new RSA team 13-14 men's record of 4:17.04. Andrew was also the anchor of the 3rd-place NCS men's 13-14 200 medley relay (splitting a 25.29). Keary's 34.40 breaststroke on the women's 200 medley relay was the second-fastest in the field and helped NCS to a 5th-place finish in the event.
Saturday evening Andrew anchored the second-place 200 freestyle relay. North Carolina Swimming finished in 5th-place (we think - final results are not posted yet).
