“A great & well run event! It is extremely difficult to manage a crowd of that size with that many variables, but the folks at USMTO and Siam did it very well. Weigh ins, medicals, etc. were done very quickly compared to other events. The brackets & bout orders were done the night before which gave our team enough time to plan logistics for the next day.”
