Actually, schools (and, presumably Colleges/Universities) can
give permission to individuals to carry, although getting it probably is right up there with finding the Lost Ark.
Houses of Worship are (I think) the only places that can post a blanket permission
to carry, negating the CPZ status of the facility. (Otherwise, get it in writing!) I don't know whether they can just put something in the "bulletin", give you a letter, or put up a sign, but I expect that the letter or a sign would be the best way.
Personally, I consider the "Houses of Worship" thing an unconstitutional interference with my rights to religious choice. While a "House of Worship" probably should (let's not get into that) have the right to post a gunbuster, the felony status of the violation is the real problem. "You can always find another Church" doesn't cut it when you're part of a minority group of some kind, and "don't ask, don't tell" really should be sufficient.
In my case, I'm Jewish. There are four Synagogues in town. Three are so far away that walking there (not something I'd do, but others consider that a requirement) is impossible. The one I belong to once asked me to attend a Friday night Service, and to "bring your gun" because some local troublemakers were supposed to be there.... Can't do that now, and "don't ask, don't tell" won't work because too many people know I routinely carry. The wife is not amused....
(Couple fries short of a Happy Meal, too....)
Anyway.... I'm still working on the board....
Boilerplate: There's a sticky at http://forums.buckeyefirearms.org/viewtopic.php?f=6&t=10097
that you should have a look at. It's not mandatory, and probably sleep-inducing, but you might learn something about how this place works, and, at least, who the little dog in my avatar is
Gunnar? Did I get you with the above sticky info? I don't recall.... If not, Welcome Aboard to you, too.
twelve: Some yelling....
The e-cig refill URL doesn't work, but mostly it's irrelevant to the post. Please avoid that sort of thing. It's OK to include your website in a signature, though. BTW, the homepage of that URL is quite interesting.
