Russ, "heartwarming" is too sappy a word to express my feelings about this endeavor of yours; suffice it to say, thank 'god' for people like you who are able to see beyond the pettyness of such things as whose equipment is superior, what genre' of music is best, etc., etc., and see the real issues; ie. providing opportunities for talented, hard-working, morally-responsible, but otherwise 'disadvantaged' kids. The main requirement, as I see it, is that they bring THEIR 50% to the table.
One of the aviation organizations that I belong to (and been an officer of at the national level), The Black Pilots of America (comprised mostly of Black ex-military and or airline pilots) runs a program similar in concept to yours. Although aimed primarily at disadvantaged, inner-city youth, it is open to all and we have always had good representation from both the White and Hispanic communities. I would not personally be involved if it were not open to all. What's important (to me) is that the individual student be willing to make the necessary investment in time and hard work.
I have donated $5000.00 towards the purchase of a trainer (C152) and each year donate matching funds for a scholarship to our aviation summer camp (usually held in Tuskegee, Al (Moten field, home of the Tuskegee Airmen), or Pine Bluff, Ak.
Without the interest and support of plain ol' individuals (such as yourself), most of these kids would probably never get or be exposed to, some of the opportunites in these somewhat exotic (avaition/music) careers.
I wish you every success and can't think of a better role-model than you and your sons (I'm guessing they'll get dragged in as well

). Man, oh man, sure wish I lived a bit closer (and were a bit younger).
