shows/events schedule

can anyone tell me where can I get a schedule for UTV/ATV/Baja/Jeep... offroad show in US, like the international car show in Toronto. I am planning on a trip to US to meet up all kinds of offroad vendors. If there is a show which all the vendors will come, that will save my time. as well as race event schedule, countrywide will be good.

thanks for your time, nice girl for you...
