Since 2001, Allen Falkner and TSD have hosted the Texas SusCon, generally considered to be the world's first and definitive annual suspension convention. Information on upcoming Texas Suscons can be found in the forums at Suspension.org. These events draw amazing artists and enthusiasts of all experience levels from all over the world to take part in suspensions and to build up technical and artistic skills.
