Salmo, I dont know what you expect to accomplish even if you couldnt be prevented from entering a "public building by a public agency". I suspect that as a renter of the facility the Department has the responsibility to monitor those entering the facility and the outcome of the usage. Demanding that the Department can only have public meetings and this meeting is public would likely only result in the tribes walking out, ending up with a open comanager meeting without one of the comanagers.
