I think you'll have to check with each State you go through with regards to pitbull breeds. (Or even counties.... Miami Dade County in SE FL has banned pitbulls.) Then have the required (if any) apparatus (muzzle?) or whatever.
You have to clear it specially with the taekwando people as well. They may need pr want to seek the "permission" of each person in the same class as you, whether they feel safe with a pitbull around.
Be sure to carry all the papers necessary, and more! Training records, certifications or courses (esp like the Good Citizen course) will help in case you have a complaint. The doctor's letters, and a copy of the law etc (I'd take several so you can leave them with a person, so they can run interference for you.
Hope you get to go and have fun!
