Go to one of the public or private western universities whose band program you respect and is near a "destination attraction." (USC, UCLA, Arizona State, Brigham Young, Oregon, etc.)
The quality of the band program always revolves around the quality of the band director. You can learn about them by asking around among your colleagues.
Hire the band director(s) to spend a half-day teaching your band(s) in a clinic situation. With enough planning and prior notice, the directors may be able to use their own facilities at little or no charge.
The event can be an expanded view of your UIL music or critical music issues that are favorite topics of the director. Be sure to include a thorough look at the entire music school and its offerings. The possibilities are unlimited.
When you weigh one more set of judges' comments against personal contact with a world-class band musician, there is no comparison.
Your juniors and seniors will learn about another choice for studying music more seriously, and they may realize that there are other opportunities they should explore. Your younger students will grow right before your eyes and bring maturity to your bands of the future.
