Bad press for the Band-Uh! I hold the Band-uh in high esteem. They have always represented a special part of UC Davis in my mind. Being such a public and visible organization, they need to keep their house "cleaner" then the general student population.
What does their org chart look like? I assume there are student leaders with administrative oversight? Is there a code of ethics beyond the principles of community for the Band-uh? And if road trips are not a sanctioned school activity, I am not sure how you can police that. Making good choices as an adult which are consistent with your personal values will keep you out of trouble. For example, if getting into a co-ed hot tub drunk and naked is not within your comfort zone, stay out of the hot tub!
