Opportunity and dates notwithstanding, my boy and I are for sure interested.
Perhaps somebody could contact the "powers that be" in Quantico. The Marines were/are always quick to help youngsters and good intentioned well do'ers. I attended many a Scout Jamboree at Fort A.P. Hill as well.
The proximity would lend itself as well to a history trip to D.C. although it may be shortlived with all the arrow slinging and hiking that would have to be done. It would require a few weeks of preparation for a few hours of enjoyment for the kids, so "volunteerism" would have to be at a peak.
And Killy--If you want to get Belvoir.....I was born there on that very base in 1966.....mention my name......I'm sure they'll remember me.
