Detroit Riverfront Conservancy

I periodically receive emails from the Detroit RiverFront Conservancy with various events that are occurring along the Detroit riverfront and surrounding area. I received an email this past week promoting their Harvest Fest fall festival on The Dequindre Cut. My family and I decided to take a drive to Detroit for what sounded like a fun family event. The email specifically stated that the River East Garage was supposed to provide free parking to guests along with a shuttle to the event (see picture below). My family and I drove 50 miles to come to this event and when we finally arrived at the River East Garage, we were told by the two young security guards employed by prostar security, that if we weren't employees or workers of the festival, we were not allowed to park there. They then pointed to a paid lot that 'we could use'. I pulled up my email and showed them where it clearly states parking was supposed to be free at this garage. They would not budge. Instead we turned around and I drove home as there was no parking available anywhere else. This is the last time we will ever try to attend one of the events from Detroit Riverfront Conservancy, complete waste of time.
