Just a quick consideration. What about setting up an early morning bike show/viewing at a local Honda dealer. Maybe they can get a local donut shop to setup coffee and donuts etc.They can invite customers and people on the fence about making a Goldwing purchase. They can setup a silent auction for the charity and then the second half of the day is a ride starting at the dealer and ending at base? You could probably get local well knows to come on the ride, you could also probably get a local radio station to broadcast from the dealer and news outlet to cover it. Just a thought.
