It is now Fall (even if the weather is still hot). Therefore, starting on October 2, 2015, the TTS club will follow the rule book that says ...
18.104.22.168. IDPA is a shooting sport based on concealed carry. All courses of fire will be shot using a concealment garment unless stipulated otherwise.
3.1. Concealment is required for all stages unless otherwise specified in the stage description. This includes standards and limited stages.
See you at the range.
