That really depends on the event organizer. INB is a Public Facilities District property, which means it is owned by the public. INB requires their leases to follow WA RCW and Spokane Civil Code, but I have had incidents where a lease denied me my civil rights and the INB did nothing to correct it. If you discretely carry the bottle in, nothing will be said unless the event you are attending decides to violate the RCW and Spokane Civil Code and inspect your person and property for arbitrarily defined contraband.
