Seems to me they might have other things on their collective minds
Y'know Richard, it isn't like they even have to DO anything, I've offered twice now, in writing, to get them help to fix the problem, all they have to do is ACCEPT the help. Simply saying "yes" isn't that difficult. They have their own charitable organization that can accept any amount of help or donations, all they have to do is allow that organization to accept help, and they haven't done that yet.
Not fixing it themselves is understandable given they have other things to do and not enough money to do them all.
But refusing to allow anyone else to fix the problem is unacceptable at least in my own way of thinking as a taxpayer and, as an American citizen who, like you, is part-owner of those cannons.
