that's an interesting point... is a tent covered?
1. OC/CPL No problem.
2. CC/CPL
"Bar" means a barrier or counter at which alcoholic liquor is sold to, served to, or consumed by
customers. page 24 of this

"Tavern", is an establishment licensed to sell beer and wine ONLY.
page 4 of this manual:

Ostensibly, this event would get a Temporary Authorization to sell beer.

IMHO, since this event is not "licensed" per se, rather it is "authorized", it really can't be considered under either of the two entities listed above. Therefore, I have a real difficult time applying the 28.425o prohibition if they wanted to charge you with a cc violation at a beer tent... as that only pertains to Bars and Taverns see:
MCL 28.425o
(d) A bar or tavern licensed under the Michigan liquor control code of 1998, 1998 PA 58, MCL 436.1101 to 436.2303, where the primary source of income of the business is the sale of alcoholic liquor by the glass and consumed on the premises.
I, however, am not an attorney and this is MY interpretation only. If you need a lawyer, please contact your state bar association.
3.OC/ without a CPL
The law states that a person, who does not fall into any of the listed exemptions, may not possess a firearm on the premises of an establishment licensed under the liquor control act. Whether a tent is "licensed" is, IMHO, arguable... the state seems to differentiate between a "license" and an "authorization". Also, I've looked up the word "establishment" in a number of dictionaries and in most (but not all) instances", an "establishment" denotes a place of business with some sense of permanence... something a beer tent really doesn't seem to have. But, since I am not an attorney, please take this as my thoughts only and definitely not legal advice.
MCL 750.234d Possession of firearm on certain premises prohibited; applicability; violation as misdemeanor;penalty.
Sec. 234d.
(1) Except as provided in subsection (2), a person shall not possess a firearm on the premises of any of the following:
(h) An establishment licensed under the Michigan liquor control act, Act No. 8 of the Public Acts of the Extra Session of 1933, being sections 436.1 to 436.58 of the Michigan Compiled Laws.
