this is something for you guys who travel or may move. mainly for BJJ guys, but also Judo guys. but if your a wrestler, when the instructor asks you, if you have had previous training and how long, what do you say? you know I'm division 1 wrestler, I'm NCAA contendor? when you go into a new school the first day, do you ask the instructor if you can wear your blue or purple belt??? is it bad to just wear your white belt when your not?
