Thus as a "membership" store is it public? In private you can conceal without permit. Come over to my house, and I can give you permission to conceal your gun on my property, or in my house.
Since no one is being very explicit with you, I will be: you are incorrect in your statement "I can give you permissino to conceal your gun on my property." This is not true.
750.227 Concealed weapons; carrying; penalty.
Sec. 227. (1) A person shall not carry a dagger, dirk, stiletto, a double-edged nonfolding stabbing
instrument of any length, or any other dangerous weapon, except a hunting knife adapted and carried as such,
concealed on or about his or her person, or whether concealed or otherwise in any vehicle operated or
occupied by the person, except in his or her dwelling house, place of business or on other land possessed by
the person.
(2)
A person shall not carry a pistol concealed on or about his or her person, or, whether concealed or
otherwise, in a vehicle operated or occupied by the person,
except in his or her dwelling house, place of
business, or on other land possessed by the person, without a license to carry the pistol as provided by law and
if licensed, shall not carry the pistol in a place or manner inconsistent with any restrictions upon such license.
(3) A person who violates this section is guilty of a felony, punishable by imprisonment for not more than
5 years, or by a fine of not more than $2,500.00.
So without a concealed pistol license, you can carry concealed in your own house, in your place of business (this means a place of business that -you own- like a personal store, not merely where you work), or on your land. You can not just "get permission" to conceal carry on someone's private property, and you cannot "give permission" to someone.
This comes up from time to time when some restaurant owner says to an OCer "Well, you can just cover that up and you can stay." If the OCer does not have a CPL, he can NOT just cover it up; the restaurant owner does not have the authority to allow you to do that, it is still illegal.
[This just had me thinking. This has kind of interesting implications for when I'm up north at my buddy's cabin. We usually all bring our firearms up there to shoot on his property. I never really thought about the fact that friends who have pistols but not CPLs would technically be illegal if they were to put their firearm in their pocket.]
