On Tuesday July 17, Mackenzie River Pizza will partner with local law enforcement agencies to host a "Tip-A-Cop" fundraiser to benefit Special Olympics Montana.  This annual fundraising event involves local law enforcement officers volunteering their time as servers to earn "tips" for Special Olympics Montana Athletes.  All proceeds from the tips are provided directly to local and state-wide Special Olympic  Montana athletes.  This year, the even will be held at both the Heights and West-End Billings Mackenzie river Pizza locations from 11 am to close.  For more information on the Special Olympics Montana and the "Tip-A-Cop" fundraiser, visit www.somt.org.
