I did BHF late last year, was an awesome time! The facility is top notch, the CRs are great and the track day includes chow. Look for the painted circles on the track that will show you the race line ( I could never see them was going to FAST, or that's what I tell myself LOL).
As O10R said ride at your pace and build confidence, get with a CR from the get go, listen and apply what they suggest. Make sure you take a rear or front bike stand as they will make you zip tie your kickstand. I was lucky since I was using warmers and had them anyway.
Will you be rolling solo? Try to bring a second hand if you can, to help with bike stands, leathers, and whatever else. Lastly, Have fun brother!!!! Take some photos and post em up when you get back!
